CONSTRUCTION OF A MODERN
CENTER FOR MATHEMATICS
Because we believe that theory is our most powerful weapon in dealing
with reality, we are expanding our Mathematical Analysis Program.
One of the first elements in this expansion is the creation of a new and
modern -building for mathematicians and physicists, which will be the
center of the Laboratory's efforts to meet by theoretical means the
challenges of the nuclear energy field.
We are seeking men with strong mathematical training at all degree
levels to participate in this expanding Numerical Analysis Programa program growing not only in staff, equipment, and facilities, but also
in concept and function. They will work in close association with our
theoretical and experimental physicists. There are openings in each of
the following fields:
RESEARCH IN MATHEMATICAL TECHNIQUES

Numerical solution of the diffusion equation for complicated geomet~ical arrays
taxes even the most powerful electronic computers. Fundamental work in iterative
techniques must lie carried out.
FORMULATION AND EVALUATION OF THEORIES

Due to the nature of physical situations now being encountered, the rough approximations which were formerly adequate must now be improved. The ultimate
test of such improvement ,is comparison with ~xperiment.
APPLICATIONS TO REACTOR PROBLEMS

A broad program 0/ computational tools lor reactor design must be effected ;ncor.porating the best available techniques. Strong interests in computation and i"
machine properties are indicated. The program at Knolls offers the atmosphere~
the equipment, the richness 0/ subject matter and the material benefits conduciv6
to a satisfying career in applications of mathematics.

THE

EDITOR,'S

NOTES

ARGUMENT, DISAGREEMENT, CONFLICT AND COEXISTENCE

In this issue we publish the text of the
legal complaint by Sperry Rand Corporation against International Business Machines Corporation as entered in court in December 1955.
We also publish the legal answer and counterclaim by IBM against Sperry Rand, as entered
in court in June 1956. These documents are
interesting to read, and they deal with i~
portant matters. People in the computer field
will watch with even more interest the evidence that will be produced and the development of the case, although of course this information will not appear if, as is more likely, the case is settled out of court.
Publication of these complaints by two of
the largest corporations in the computer field
against each other, we realize, is to some extent unconventional. It runs counter to a
rather deep-seated tendency in any social unit,
ranging from the family, or the group of people in any professional field, up to the country as a whole: the desire to gloss over, take
little notice of, the sea~ side of life, where
important socially accepted principles have
apparently not been followed. In a newspaper,
for example, a f~ank admission by someone in
authority that something has happened in his
area of responsibility that should not have
,happened invites unfriendly and unfair attack.
It rarely calls up the more scientific and
charitable attitude "He did it and he's sorry;
maybe he has learned something."
In spite of the fact that the present conflict deals with the less pleasant side of co~
petition in the computer field, we believe
that discussion of it, airing of it, is beneficial and not harmful. Computer people and
the public in general, in regard to this and
similar questions, cannot make up their minds
in a vacuum, without data, without knowledge
of things that have actually'happened. The
texts of the complaints, of course, contain
no evidence; it is the evidence to be offered
that will be crucial.
In spite of the conflict there is a great
unanimity about the way in which the conflict
will proceed and tdll be settled.' The procedure is knot1.D and agreed on. Employees of the
contending corporations will continue to talk
amicably to each other at meetings of computer people. The conflict is put into a co~
partment and localized. Everyone is agreed
- 4 -

that no shooting over the argument will occur.
The two corporations and everyone else have
accepted coexistence as something that will
inevitably happen.
In this issue we also publish a computer
science-fiction story, ''Requiem''. It discusses
another kind of conflict and pictures another
kind of mentality -- one which would not accept coexistence even if not to do so meant
self-destruction. It also points out some of
the logical consequences of computers. Scientists and computer people are not immune from
the social consequences of the science and
computer knowledge which they discover, and
they have a social responsibility for what
they find out. And the pursuit of knowledge,
the skillful extraction of the secrets of nature, with complete disregard of how these
secrets will be used, is just as academic and
can ~ell be far more harmful than to spend
forty years of one's life in unraveling the
grammar of ancient Greek.

Our current military contracts support a broad
range of advanced work in the fields of modern communications, digital computing and data-processing, fire control systems, instrumentation and test equipment. In the
guided missile field, Ramo-Wooldridge has technical direction and systems engineering responsibility for the Air
Force Intercontinental and Intermediate Range Ballistic
Missiles. Our commercial contracts are in the fields of
operations research, automation, and data processing. All
this development work is strengthened by a supporting
program of basic electronic and aeronautical research.
PROJECTS

RESEARCH AND DEVELOPMENT PERSONNEL The above
curve shows the growth in Ramo-Wooldridge personnel
which has taken place since our Progress Report one year
ago. A significant aspect of this growth is the increase in
our professional staff which today is made up of 135
Ph.D:s, 200 M .S:s and 265 B.S:s or B.A:s. Members of the
staff average approximately ten years' experience.

FACILITIES Within the past few months, construction has
been completed at our Arbor Vitae complex, which now
consists of eight modern buildings of 350,000 square feet,
four of which are illustrated at the bottom of the page.
Nearby is the R-W flight test facility, including hangar,
shop, and laboratories, located on a 7-acre plot at International Airport.
To provide ,additional space for our continuing growth,
construction (has been started on an entirely new 40-acre
Research an~ Development Center, located three miles
from the Arbor Vitae buildings. The photograph above is
of a mod~l of the Center, which we believe will be one of
the finest research and development facilities in the country. The first three buildings, now under construction, will
total 250,000 square feet.
A second major construction program is underway on a
manufacturing plant for quantity production of electronic

As we look back on our first three years of
corporate history, we find much to be grateful for. A wide
variety of technically challenging contracts have come to
us from the military services and from business and industry. We have been fortunate in the men and women who
have chosen to join us in the adventure of building a company. We are especially happy about the six hundred scientists and engineers who have associated themselves with
R-W. Their talents constitute the really essential ingredient
of our operations. We plan to keep firmly in mind the
fact that the continued success of The Ramo-Wooldridge
Corporation depends on our maintaining an organizational
pattern, a professional environment, and methods of operating the company that are unusually well suited to the
special needs of the professional scientist and engineer.

TWO ELECTRONIC COMPUTERS SHARE
A SINGLE PROBLEM
National Bureau of Standards
Washington 25, D.C.
Data-processing shared by two interconnected electronic digital computers has bee n
successfully performed- at the National Bureau
of Standards. SEAC and DYSEAC, two high-speed
computers designed and built at the B u re a u,
worked cooperatively on a common task to demonstrate program-controlled machine intercormnunication in which coordinated programs t~ere read
into both machines. The problem simula te d a
situation where stock transaction reports are
tabulated and summarized for fiscal ac counting, and then forwarded for posting to inventory control records elsewhere. The ex periments were carried out by the -Bureau IS d a t a
processing systems laboratory as part 0 f a
cooperati ve program wi th the Navy Bur e a u of
Supplies and Accounts to investigate the application of electronic techniques t o t h e
problems of supply management. The experilDEDts
showed that two digi t'al computers need not have
identical operating characteristics to work
together, provided that one of them has th e
necessary control flexibility.
Typical applications of digital compute~
as data processors involve replacement of many
small specialized machines by a single aut 0matic system. However, for massive pap e rhandling operations, or for large-scale activi ties requiring the processing of the sam e
data for different purposes at differen t locations, the use of roore than one high-speed
data processor may be necessary. For instance,
in the far-flung supply organizations of the
armed services, expediting flow of mformation
is essential to efficient supply management.
Automatic cODlDunication between machines has
been foreshadowed by direct input and outp u t
provisions so that the computer continues with
other useful work while transfers of information between it and external devices are in
process, and by tape-proce~sing devices where
search is under the program control of a computer. In this example, however, the interconnection is between a computer serving as
the nucleus of a processing system and othe r
parts of the same system.
.

they can cooperate on a common task. For example, a versatile large-capacity data-processor at a materiel control center might receive
data fed to it automatically by smaller computers located at various supply depots. The
supervisory processor (at the center) mig h t
so control the system-wide processing that it
would accept data from each of its repor ti n g
sources in a scheduled sequence but would also
be free to accept and handle priority requests
for supply action from any of the depots at any
time.
For the kind of interac tion where bot h
information and exchanges of control are transferred between computers, the question of programmed control versus automatic interruption
is particularly important. Programmed control
depends to a cons iderable extent on hum a n
anticipation of when and how the interchanges
should occur; however, if two or more systems
are to interact automatically wi thout h urn a n
intervention, provision must be made for automatic interruption of a program in process in
order to turn to the new information jus t received from another system. DYSEAC provides
such interruption properties.
DYSEAC tfas designed at the National Bureau of Standards for the Department of Defense
to serve as the nucleus of a generalized feedback control network. This computer incorporated a number of operating features enabl in g
it to respond automatically to informa~nfrom
remote external devices. These 0 pe rat i n g
features include manual-monitor f ac iIi ties,
program control flexibility, and s p e cia 1
input-output controls. Together they provide
DYSEAC wi th unusual properties of concurr e n t
operation, self-regulation, and interruptibility which enable it to interact effectively
with another computer.
During a period of three weeks the two
machines, SEAC and DYSEAC, were available for
experiments in interconnection. The prog ram
chosen for the experiment was a new method of
sorting, merging, and posting of records. In
the problem, stock transaction reports we r e
tabulated and summarized by SEAC, then f 0 rwarded to DYSEAC for posting. In the SEA C
program for running this problem, as de t ail
items were identified as belonging toe a c h
file section in a scheduled order they we r e
transferred to DYSEAC for posting there.
In
c:ddi tion, after each complete set of de t ail
items for a p~rticular file section had b ee}l

Most general-purpose electronic compute~
employ a generally compatible digi tal language,

Figure I -- Flow diagram of problem shared by the interconnected computers, SEAC and DYSEAC.
In this problem, stock transaction reports are tabulated and summarized by SEAC, then fo~varded
to DYSEAC for posting. Results of this experiment demonstrate clearly the ability of DYSEAC to
respond to monitor signals originating in SEAC and to interrupt its program in order to receive
and process the detail data from SEAC. DYSEAC worked on an independent sequence of typical_machine operations, silD.lllating a concurrent program, while waiting for SEAC to transmit data.

processed, SEAC transmitted a special end-of-·
set flag to DYSEAC. The coordinated DYSE A C
program called for (1) responding to the SEAC
transmi tted signal, (2) reading-in the message
from SEAC .. (3) determining whether th.e message
was a detail item or an end-of-set f13g, and
(4) either tallying the appropriate mas t e r
file item ill the first case, or reading 0 u t
one file section and reading in the next in the
case of the flag.
A cable between the SEAC building and the
trailer van housing DYSEAC provided interc 0 nnection through a regular input-output terminal
of each machine. Information transfers we r e
ini tiated and terminated by trans mis s ion of
control signals between the two machines. Whenever a SEAC output instruction called for selection of the particular output use d for
transmission to DYSEAC, a 62-volt preparatory
signal lfas sent from the SEAC external selector
uni t to DYSEAC. This signal activated appropriate moni tor operations in DYSEAC. As s 0 0 n as
DYSEAC was ready to accept the data, it transmitted a 62-volt signal to SEAC. Only upon receipt of this signal lfas SEAC able to proce e d
wi th its next instruction. In effect, SEA C
continued trying to complete this 0 u t pu t instruction until DYSEAC signalled readine s s to
accept the transfer.
This dual machine interconnection utilized
both the special program control and the man u almonitor features of DYSEAC. In terms of program
control, DYSEAC is a three-address automatically
sequenced machine; choice between 0 n e of two
counters as the source of the address 0 f the
actual next instruction is determined by c 0 ntrol-code digits in the ins truction being ex ecuted at any operating time. In addi t ion, a

tion specified by the address-storage register.
The instruction selected in this manner the n
indicates in its program-control -digits whic h
of the two counters is to be used next. In this
way, it can either return DYSEAC to a program
that had been discontinued during the interruption or initiate an entirely new seque n c e of
opera~ions.

For the DYSEAC-SEAC interconnection, monitor switch settings were arranged so that~n
receipt of the preparatory signal from SEA C,
DYSEAC at its next breakpoint read in one i nformation word to a predetermined m e m 0 r y
address aud took its next instruction from the
location indicated in the address storage register. This next instruction was a "file" order which recorded both counter settings, reset
the proper counter to the ini tiation 0 f the
routine for the processing of the data fro m
SEAC and transferred control to that counte r.
Upon completion of the processing of anyone
set of data from SEAC, DYSEAC would return t 0
the sequence of operations it had been performing immediately prior to each interruption.
When the coordinated programs had bee n
read into both machines, SEAC was set tor u n
but was inhibited by a control signal from DYSEAC. When DYSEAC had completed reading in tire
first file section and had proceeded to 0 th~ r
independent operations, a release of con t r 0 I
enabled SEAC to start. As soon as the S E ACprocessed data were ready for posting, the y
were converted t~ the proper format for DYSEAC,
transmi tted, and checked by DYSEAC t 0 see
whether there had been garbling in transmission.
The receipt of data simulating a detail i t e m
resulted in a tally count for the appropriate
master item in the file section.

Manual-monitor operations are those th a t
are carried out by the machine l"hen c e r t a i n
prespecified conditions arise in the course of
the machine's internal program and s imul t a neously in external switch settings. The switch
settings are controlled either by the machine
operator or by d-c voltage signals originating
in external devices at any distance from DYSEAC.
Thus, the machine can monitor its internal program to determine precisely when special operations requested by an external source are tohe
performed.

Several runs of the shared program w ere
successfully made, and the "posted" file s e ctions lfere printed out on a DYSEAC mag net ic
wire cartridge. These results clearly dem 0 nstrated the abili ty of DYSEAC to respond to the
monitor signals originating in SEAC and to interrupt its program in order to rece i v e and
process the detail data from SEAC. The -t w 0
machines were thus made to work cooperatively
on the common task that involved preliminary
processing of data by SEAC, transmiss ion 0 f
these data and program information from SEA C
to DYSEAC, and further processing by DY SEAC.
DYSEAC worked on an independent seque nee of
typical machine operations, simulating a co ncurrent program, during the intervals in which
it waited for SEAC to transmit data.

If the switch settings that are controlled
by d-c voltages from the external device indicate that the device is ready, DYSEAC Ifill then

SP:ECIAL ISSUES OF
~~COMP,UTERS

AND
AUTOMATlON"

The June issue of "Computers and Automation"
commencing with June, 1955, is a special issue,
"The Computer Direc tory. "

MANUSCRIPTS
We are interested in articles, papers,reference
information, science fiction, and discussion relating to computers and automation. To be considered for any particula~ issue, the manuror~t
should be in our hands by the fifth of the preceding month.
Articles. We desire to publish articles that are
factual, useful, understandable, andin~sting
to many kinds of people engaged in one part oranother of the field of computers and automation.
In this audience are many people who haw expert
knowledge of some part of too field, rut \ViI) are laymen in other parts of it. Consequently alaiter
should seek to explain his subject, and shQw its
context and significance. He should define unfamiliar terms, or use them in a way that make s
their meaning unmistakable. He should identify
unfamiliar persons with a few words. He shruld
use examples, details, comparisons, analogies,
etc., whenever they may help readers to understand a difficult point. He should give data
supporting his argument and evidence for his
assertions. We look particularly for articles
that explore ideas 'in the field of computers
and automation, and their applications and implications. An article may certainly be contr~
versial if the subj ect is discussea- reason abl~
Ordinarily, the length should be 1(0) to 4000'
words. A suggestion for an article should be
submitted to us before too much l~rk is done.
Technical Papers. Many of the foregoing zequnements for articles do not necessarily apply to
technical papers. Undefined technical terms,
unfamiliar assumptions, mathematics, circuit
diagrams, etc., may be entirely appropriate.
Topics interesting probably to only a few
people are acceptable.
Reference Information. We desire to print or reprint reference information: lists, roste~ abstracts, bibliographies, etc., of use to computer people. We are interested in m a kin 9
arrangements for systematic publication from
time to time of such information, with other
people besides our own staff. Anyone who,~
like to take the responsibility for a type of
reference information should write us.
Fiction. We desire to print or reprint fiction
which explore~ scientific ideas and possibilities about computing machinery, robots, cyberne1.ic.s.. autoJDation:. etc.. anq t;heir illtllicatials,
and \vhich at the same time is a good story. 0rdinarily, the length should be 1000 to 40W tQ.'ds.
Discussion. We desire to print in "Forumf' brJff
discussions, arguments, announcements, news,
letters, descriptions of.remarkable new developments, etc., anything likely to be of substantial interest to computer people.

REQUIEM
K. W,. RENNETT

Lake Zurich, Ill.
It was one of the two most danger 0 us
desks in the world. Cutter ran his pal m
gently across its smooth g r e ens u r f ace,
brushed his fingertips lightly across the big
green buttons scattered like organ stops across the desktop. His scrubbed finger ~raced
the letters beneath the buttons. "Moscow"
was a big button. Beneath it ranked lesser
buttons lettered "Murmansk", "Leningrad", "Baku",
and the rest. Then there was a "China" sector
with black buttons and an "Indian" sector with
buttons that were red and small like beetles.
And more, linked with fat armored cables to
the ranks of computers that crowded the walls
of the room.
Dangerous and clean and beautiful, this
desk, like a loaded Luger pistol. And e a c h
time he pushed a button, four hydrogen bombs
~uld waken to life in a distant place.
A split
sec/ond they would lie in their dark cradles beneath the JOOuntain ice and windpacked s now,
listening to the stream of measured impulses
of latest calculation from these com p u te rs.
Then their tail pipes would spurt comets 0 f
flame and they'd howl aloft and be gone atfour
times the speed of sound through the strato--Sphere on an invisible guiding arc of computer
signals, fantas~ically rapid and fantastically
accurate. When the bombs touched earth again,
a city would die. Not bravely, but with co~
pleteness.
The alarm bell tinkled softly. It was
regulated to tinkle softly to prevent alarming
the guardian of the buttons. In accordanc e
with regulations, Joe Cutter extended a hovering hand over the "Moscow" button and with the
other unsheathed a loaded .45 Colt aut 0 ma tic
and centered its black barrel on the door. The
pmumatic ,door hissed up. A general, t he las t
Generai, entered, smiling determinedly. Cutter
'sighed and subsided into a gray little man behind an oversi~ed desk. He touched his helmet
in half salutation and reholstered the .45
without getting up. The General closed the
pneumatically operated steel slab. .be caugh t
a remembered glimpse of clothes racks behind
the General as the grey steel slab slid down.
The General marched to one of the three
fat uphols tered chairs. He j ackknifea himself
to a sitting position with military reluctance.
"Good mrning, Cutter," he beamed.

"Good morning, General," s ai d Cut t e r.
The General winced. It wasn't much fun, being
the last General, Joe imagined. Like being an
extinct species of moose preserved in a zoo.
"Everything all right, Cutter?" the General demanded.
Joe himself winced, this time. The General asked the same question each morning. He
had for three years, ever since the co mp u te r
room and desk installation had been completed
following signing of the disarmament pact. And
it was a ridiculous question. The nation.auld
be on its knees before anything would be a 1lowed to go atf.ry in this crowded roomful 0 f
computers and maps and lethal buttons.
The General rolled on with heavy cheer,
"Good, Cutter. Must keep shipshape. Particularly now. If the citizen exchange agreement is a fake, it means the enemy is smokescreening us for good reasons. Might be the
Big Attack."
Cutter tvavered between pity and bored dislike. The last General, fending off a d is armed tforld. For an Army he had Cutter, and
his shift-mates. a battery of the greatest
electronic brains technology could pro d uc e ,
and a handful of technicians; all carefully
buried from the world. A man who'd commanded
thousands and tens of thousands. His only visible command at the moment, during this shift,
a ~mall ratlike man wearing a steel helmet fuat
was several sizes too large, hunched behind an
oversize desk and several rows of gray steel
computers that chuckled electronically over
the belly warmth of their live circuits. It
must seem like commanding a homicidal mouse
and a line of pinball machines, Joe decided.
"The Russki's are disarmed. General,"
Cutter said with gentleness. "And they're
sending their top-men" here to prove faith."
The worn gambit still brought flame to
the General's eyes. His raison d~~e. The
old eagle gaze swept the room, iis four grey
walls with their charted ballistic curves and
maps and alternate attack plans ruled in red
and yellow and black lines across the mottled,
blue of the maps.
"We have a room here 40 miles from Wash-

ington, D.C., Cutter. And we have weapons.
You may be completely certain that the Ene my
has a similar room. And similar 1 au nch i n g
sites, perhaps in the Urals, or perhaps in Siberia. But they have them and you can count
on it they could blanket us with hydrogen banbs
in a split ttdnkling. As we can them." .
"Intelligence never found their room or
th:eir sites, General," Cutter murmured.
"No more than their inspection teams have
been able to locate this place -- we hope. And
tfhat inspection team tfould dare go slink in g
through the bedroom of the Vice President's
tdfe looking for a secret room? Faugh! 0 f
course they have a room! An elementary tactic,
Cutter."

no more wars. Really. No more desk with buttons. No more Dynamite Joe •. Back to a $95 a
week clerical job.
''Yes! Just like that! They've signed!"
The President threw his handful of papers ceilin~'lard and they sailed down like big snowflakes
across the floor and over the Number Four reserve computer and even -- Joe felt a kind of
distaste at the sight -- across the spotless
desktop. The General departed from a posture
of affability and began policing up the sheets
of paper in a lost manner.
"It's not a trick," said the President into the silence.
The General was beginning to snap back.
"Why not? We can't knot'l until their people begin to arrive here."

"Well, General, if the exchange plan goes
through, we'll have mass exchanges of peoples
between the two countries with voting rig h ts
while in residence. Who'd have time to fight?
And they'll be sending their top men here -their leaders. What a struggle they'll have
before they'll accept that provision1"

"Of course," said the President, "And the
first plane load left Kharkov this morning.
Their Premier and the Party Secre·tary are aboard,
and it'll be a kind of triumphal tour witi stqs
en route."

"Any overtures thus far may be a trick,
Cutter. A sly trick."

The General marched to the President's
side in dawning anger.

Cutter shrugged and stared at the buttons.
Superior or not, he was getting pretty sick of
the General.

"That's no proof. We can't deactivate the
room. Not yet. The program must run for at
least two or three more years before we'll be
sure. "

"Have you dusted, Cutter?"
General.

demanded the

"Sure," said Cutter, and then remembered
to add the "Sir". The General donned a white
glove and began po~ing behind the Number Three
reserve computer. Cutter rolled his eyeballs
at the ceiling. The alarm bell tinkled. Dynamite Joe Cutter donned his helmet and aimed
the .45 at the door, dropping the .45 in the
process and picking it up again. The General,
watching, winced only slightly. His control
t'las improving, even for a General, Joe decided.
The gray steel slab of door hissed up, r~
vealing a closet interior carpeted with female--type shoes. The President stood among the pumps
and sandals. He was a big, silver-haired man
and he was smiling. Not a campaign smile, but
a deep, happy smile. Joe smiled back. He liked
the President. Whatever the guy's position, he
really cared for all kinds of people. Little
people like Joe. Joe figured the President even liked the General.
. The President grinned at the .45. "Don't
shoot, Joe," he said. "The Cold War is over.
The exchange agreement is signed."
Joe couldn't help the stunned feeling. If
they'd signed the exchange agreement, it meant

"I can't take that chance, Hal," said the
President. "If a truce team located this room
now, there'd be a five minute war with nothing
left standing on either side. I want it eli~
inated now -- immediately. I'm taking what you
military people used to call a calculated risk."
"Calculated risk?" the General's face
went turkey color and Joe noted that he was
screaming, though in a military manner. "It's
calculated insanity: If they've got weapons .
enough -- why if they had two bombers, or two
guided missiles, or -- two beanshooters, we'd
be helpless. Helpless!"
Joe put his helmet back on.

"Take that helmet off~ you icUot," snarled
the General. "For God's sake, Mr. President,

"We're deactivating this room, General.

already on that plane:"
'You've gone mad. This is what they've

DATA

PROCESSING

THE

MIDWEST

NEIL D.

~ACOONALD

Following the trend tourard the automation
of data processing and computing operations, mare
and more manufacturers, business firms, and scientific organizations are installing electronic
data processing systems. Installations of such
systems produced by International Business Machines Corporation throughout the country have increased sharply in the last year and a half; s~h
machines are being applied to a J.vide variety of
both scientific and commercial problems. In the
Midwest alone, there are nearly a hundred of the
company's "electronic giant brains" not'/ at work,
t\'1 th many more on order.
IBM's computers include the large-scale IBM
701, 702, 704 and 705 Electronic Data Processing
Machines, and the medium-scale IBM 650 Magnetic
Drum Data Processing Machine.
FollOlving are examples of the many fields
in which IBM electronic data processing systems
are being applied in the Midtvest.
INSURANCE
A company that will probably be one of the
biggest users of IBM data processing equipment
in the fire and casual ty insurance indus try is
State Farm Mutual Automobile Insurance Company
of Bloomington, Illinois. This company will eventually use 24 IBM 650 Magnetic Drum Data Process ing Machines. State Farm nOlY has two of the
machines installed in its home office, one each
in two regional offices, and 20 on order for its
12 regional offices thrcughout the U. S. It is
expected that deliveries will be completed in
1957.
State Farm's applications for the 650's include selective underwriting, automatic premium
rating, policy reports and internal and external
s ta tis tics.
The first 650 installed by an insurance company in the Chicago area is at the Zurich-American Insurance. Companies. .Its ini tial tasks include consolidation of collection data, and recording and classifying of transactions by branch,
agent, and type of insurance. This 650 combines
and accelerates operations formerly requiring
four separate machines. Its use will be extencirl
to recording of claims and preparation of los s
ratios.
The Iowa Mutual Insurance Company, DeWitt,

OPERATIONS

Iowa, uses its nel'l650, received early thi's
spring, for automatic premium rating of automobile policies. This 650, the first in the
fire and casualty field in Iowa, will han dIe
myriads of insurance calculations at h i g h
speeds, enabling employees to be assigned to
less routine and more creative work. T his
"elec tronic clerk" will also do payroll, u nearned premium calculation, agents' commdssion
computation and various statistical distribution summaries and analyses. Iowa Mutual plam
to extend the machine's activities into the
fire, burglary, general liability, and workmen's compensation divisions of the company.
Northt1Testern Mutual Life Insurance Company of Milwaukee, Wisc., plans to add a 650
to its present line of IBM equipment this s~
mer. Initially the machine will compute annual dividends for more than 1,600,000 policies.
Another application will be accounting and calculation of 80,000 mortgage loans, involving
monthly payments of principal, interest and
taxes.
Employers Mutuals of Wausau, Wisc., is putting a 650 into operation and expects it will
greatly facilitate handling of voluminous records and statistics of the insurance business.
nvo initial applications are automobile policy
rating and premium distribution reports.
. An insurance company with a decentralized
policy of operation, Hardware Mutuals, will begin using a 650 late this year, for premium,
loss, and expense distribution figures necessary for internal company reporting, annual statement, tax purposes, and insurance bureau r equirements. This company has 14 policywriting
offices that send data to the home office in
Stevens Point, Wisc., where it is converted to
a medium that can be machine processed. Hardware Mutuals does all selling through 675 direct salesmen, and figures for any individual's
territory will be obtainable very quickly with
the 650.
The Royal Neighbors of America, Rock Island, Illinois, a fraternal life insurance co~
pany, uses a 650 to audit 4,700 camp reports
per month, involving the processing of abo ut
half a million punched cards. Other systems to
be converted to machine operation are .automatic
preparation of bond schedules for the annual
statement, valuation of certificate reserves,

of the loan account.

counterparts of the 702 and 705. The investigations section gives mathematical and computational support to the aircraft gas turbine
division of GE, an~ to all divisions of the
company upon request. One of the 704's is at
Lynn, Mass., and the other machines are i n
Cincinnati, where they occupy the country's
first permanent industrial building designed
solely to house computers. The 701 at C i n cinnati will shortly be replaced by an additional 704.

Nationwide Insurance Company has a 650
in operation at its home office in Columbus,
(hio, used primarily to check rates on new
policies and to determine rates on r en ew a 1
policies. This information arrives a t the
home office via transceiver network from ten
regional offices. The transceiver is an IBM
,machine which makes possible duplication 0 f
punched cards over telephone and telegraph facilities. The information received at Colu~
bus is processed in the 650 and returned to
the respective region where the results are
punched in the same card originally used to
transmit the policy information.

The Evendale Opera ting Department of General Electric Company's jet engine plant near
Cincinnati received delivery of a 650 1 a s t
February. By March 5 the payroll of two departments had been completely converted from
conventional machine accounting procedures to
the 650. Other applications are being planned,
including general ledgers, budget statements,
and production scheduling.

An IBM "giant," the 705 Electronic Data
Processing Machine, is scheduled for installation this SUJIUOOr at the St. Paul Fire and
Marine Insurance Company, St. Paul, Minnesota.
The company plans to use the computer for accounting and statistical operations.

General Electric Company's component motor department in Fort Wayne has a 650 which
solves complex motor design problems and handles the weekly payroll and indirect manufacturing expense reports. The computation of 100
motor design variations, completed in t h r e e
hours, would require more than six months with
a desk calculator.

HOSPITALIZATION
Michigan Hospital-Medical Service has on
order, for its general office in Detroit, a
705 which will be put to work on a gigantic
task of up-dating records for 1,350,000 subscribers on a daily basis. Many complicated
statistical reports, hitherto unobtainable or
prohibitively expen~ive, will be made available.

Minnesota Mining and Manufacturing Company will install an IBM 705 at its general
office in St. Paul in September of this year.
One of its .first tasks will be the computation
of sales statistics. Other assignments include
raw and semi-finished materials inventory, payroll and operating expense reports.

MANUFACTURING AND HEAVY INDUSTRY
The International Harvester Company's
motor truck division at Fort Wayne, Indiana,
recently installed an IBM 705 to serve as a
centralized data processor for four pIa n. t s,
including that of the farm tractor division
in Louisville, Kentucky. In this installation, tremendous savings in time have been effected on such problems as cam design, bearing
load, gas pressure and other engineering calculations.
The West Pullman Works of International
Harvester Company, on Chicago's South Side,
