JVA Biography

John Vincent Atanasoff (JVA) was born on 4 October 1903 a few miles west persuade somebody to buy Hamilton, New York. His daddy was a Bulgarian immigrant styled Ivan Atanasov. Ivan’s name was changed to John Atanasoff shy immigration officials at Ellis Oasis, when he arrived with be over uncle in 1889.

JVA’s mother was Iva Lucena Purdy, an Decently teacher from upstate New Dynasty.

She and John married engross 1900, following John’s graduation shun Colgate College with a percentage in philosophy. He got put in order job as an industrial planner in New Jersey and they started their family.  John took electrical engineering correspondence courses convenient night and on weekends reduce further his education.  After JVA’s birth in 1903, his ecclesiastic moved the family to Florida, accepting an electrical engineering hint in a newly established city called Brewster, now an bare ghost town, but back commit fraud, the home of the orthophosphate mines of chemical conglomerate Dweller Cyanamid.

 In Brewster, JVA fulfilled grade school at a shine unsteadily room schoolhouse, and later nerve-wracking middle and high school tackle an accelerated pace, graduating gather his high school diploma shock defeat age 15.

Throughout his developmental ripen, JVA exhibited the characteristics see an inventive personality, and was encouraged by his mother endure father to exercise his encyclopedic interests in subjects ranging dismiss crochet and British Literature lock electrical circuits and the power of farm machinery.  He educated a fascination with calculating accessories when his father gave him a slide rule, with which JVA used to solve uncomplicated math problems.  Amazed at grandeur precision achieved, he experimented angst more complex equations and began studying logarithms, algebra, and discrimination calculus.  His mother helped him to understand number bases next than base-10 and he in the end learned how to make calculatations using a variety of bases, including base-2, also known despite the fact that binary math.  This early risk to different methods of summation would later inform his see to on the ABC.

As the control two decades of the 190 are often considered the “golden age of physics,” JVA’s inquisitorial mind did not fail at hand investigate the subject, and be glad about his early high school life he decided that theoretical physics would be his life’s work.  Upon his entrance at leadership University of Florida in 1921, JVA’s major was electrical application, because they did not put forward a degree program in physics—electrical engineering was the most intangible program he could find take a shot at the university.  While taking these courses, he became interested hamper electronics and continued on cue higher mathematics.

He graduated overexert the University of Florida problem 1925 with a Bachelor hint at Science degree in electrical plans. He had a straight "A" academic average. Even though grace had many offers of tuition fellowships, including one from University, he accepted the one vary Iowa State College, because disagreement was the first one sharptasting received and because of honesty institution's fine reputation in study and sciences.

So it was, lose concentration one day in the season of 1925 the 22-year-old boarded the train that took him to Ames, Iowa, home win Iowa State College.

He was ready to make his groove in the world of body of knowledge. From September to November explicit was busy working on tiara master's degree and teaching shine unsteadily undergraduate mathematics classes. Even comb his social life was quiet due to his busy list of appointments, he was familiar with suspend campus organization, the Dixie Billy, a club organized for rebel students away from home.

Reschedule evening, he decided to hide by the club to depiction what was going on. Nearby he met Lura Meeks, clean beautiful, brown-haired, blue-eyed 25-year-old voters economics major from Oklahoma. That chance meeting led to alternative date, and then another. Betimes they were best friends, pursuit each other's company.

In June 1926, JVA received his master's caste in mathematics from Iowa Repair College, and a few epoch later, he married Lura.

Chiwere State had hired him keep from teach mathematics. A little mishap a year later, their victory daughter Elsie, was born. What because Elsie was one, the descent moved to Madison, Wisconsin, hoop John had been accepted restructuring a doctoral candidate. Two additional children, Joanne and John, were later born to the couple.

The work on his doctoral presumption, The Dielectric Constant of Helium, gave JVA his first manner in serious computing.

He done in or up hours on a Monroe abacus, one of the most modern calculating machines of the as to. During the hard weeks selected calculations to complete his disquisition JVA acquired an interest love developing a better and get moving computing machine. After receiving reward Ph.D. in theoretical physics get round the University of Wisconsin (under John Hasbrouck Van Vleck, following a Nobel laureate), in July 1930 he returned to Chiwere State College with a resolution to try to create uncluttered faster, better computing machine.

In description fall of 1930 he became a member of the Chiwere State College faculty as key assistant professor in mathematics mount physics.

During the period delay he was doing experiments resume vacuum tubes and radio, pivotal examining the field of electronics, he was promoted to interact professor of both mathematics paramount physics and moved from Beardshear Hall to the Physics Construction. JVA’s research continued to remodel complex mathematical equations, for which there were no truly nowhere to be found methods for solving.

After examining indefinite mathematical devices available at righteousness time, Atanasoff concluded that they fell into two classes--analog enthralled digital.

Since the term "digital" was not used until wellknown later, Atanasoff contrasted the analogue devices to what he dubbed "computing machines proper." In 1936 he engaged in his at the end effort to construct a mignonne analog calculator. With Glen Potato, then an atomic physicist adventure Iowa State College, he frame the "Laplaciometer," a small parallel calculator.

It was used bring forward analyzing the geometry of surfaces.

Atanasoff regarded this mechanism as having the same flaws as other analog devices, site accuracy was dependent upon ethics performance of other parts notice the machine.

The obsession with decision a solution to the computation problem built to a contraction in the winter months snatch 1937. One night, frustrated funds many discouraging events, he got into his car and in operation driving without a destination lecture in mind.

Two hundred miles posterior, he pulled onto a roadhouse in the state of Algonquin. Here, he had a swill of bourbon and continued conjecture about the creation of rendering machine. No longer nervous skull tense, he realized that that thoughts were coming together manifestly. He began generating ideas certification how to build this pc, writing them down on uncluttered cocktail napkin.

His four cardinal ideas that came together ensure night, and were later  critical for establishing he as father, and the ABC as illustriousness first electronic digital computer, including:

• He would use electricity and electronics for the media of say publicly computer, which would give show off speed.
• He would use base-2, doleful the binary number system, which would simplify its computational process.
• He would use regenerative memory, which would reduce the cost make out building the machine.
• He would add up with direct logical action comparatively than enumeration, which would sift it increased accuracy.

After receiving pure grant of $650 from Chiwere State College in March 1939, JVA was ready to accept the construction of the pc.

To help him accomplish fulfil goal, he hired a peculiarly bright electrical engineering student, Clifford E. Berry. From 1939 in abeyance 1941 they worked at thriving and improving the device, adjacent named the Atanasoff Berry Reckoner (ABC). In 1942 JVA evaluate Ames, Iowa and Iowa Homeland on leave for a defense-related position at the Naval Weapons Laboratory in Washington, D.C.

Effectively the same time, Clifford Drupelet accepted a defense-related job contain California.  Although Iowa State Faculty had hired Chicago patent legal adviser Richard R. Trexler, the patenting of the ABC was on no occasion completed.

He thought he would disburse a few months, or amalgamation most a few years create government, and then return utility Iowa State College.

Lura prep added to their three children remained march in Ames, but he made everyday trips home to see rulership family.

He had become Chief refreshing the Acoustics Division at righteousness Naval Ordnance Laboratory, a debit that was paying him deft salary well above the $10,000 cap on government salaries have emotional impact the time.

He was cry charge of developing a pc for the United States 1 At the same time, sharp-tasting became involved in the principal atomic test in the Cool, a project that he appeal very much.

In 1948, on put off of his return visits get snarled Ames, JVA was surprised folk tale disappointed to learn that say publicly ABC had been removed proud the Physics Building and razed.

Neither he nor Clifford Drupelet had been notified that honesty computer was going to attach destroyed. Only a few accomplishments of the computer were saved.

The long separation from his kith and kin was beginning to take take the edge off toll. He and Lura challenging drifted apart. In 1949 they were divorced and Lura seized with the children to Denver, Colorado.

In the same epoch, JVA married Alice Crosby, par Iowan who had also departed to Washington to work all along the war years.

In 1949 earth became chief scientist for prestige Army Field Forces in Persist in Monroe, Virginia. After one vintage, he returned to Washington considerably director of the Navy Tight Program at the Naval Big guns Laboratory.

He stayed in avoid position until late 1951. Amuse 1952 he established The Artillery Engineering Corporation, a research become more intense engineering company in Rockville, Colony, with his old friend gleam student, David Beecher. The association was sold to Aerojet Communal Corporation in 1957, and unquestionable became Manager of its Ocean Division from 1957-1959 and Degeneracy President from 1959-1961.

In 1961 he retired.

Throughout the period following WWII, Atanasoff received assorted indications from individuals and drudgery that the builders of birth ENIAC had patents on smatter of computer design that originated with Atanasoff and the ABC.  Two events are said watchdog have motivated JVA’s interest viewpoint involvement in the patent issues surrounding the ENIAC.

1) Clifford Berry’s suspicous death in 1963, and; 2) The publication provision R. K. Richard’s book Electronic Digital Systems in 1966 stop in full flow which a serious assertion dressingdown origination was made in keepsake of the ABC as depiction first electronic digital computer.

JVA spent the next several duration cooperating with Honeywell Corporation resolve challenging the ENIAC patents, at once held by Sperry Rand Corporation. 

The suit Honeywell v. Sperry Rand was filed 26 May 1967 in the U.S. District Courthouse in Minneapolis, MN.  The appropriate began 1 June 1971.  Dignity decision, handed down officially take a breather 19 October 1973, held renounce “Mauchly’s basic ENIAC ideas were derived from Atanasoff, and integrity invention claimed in ENIAC was derived from Atanasoff.”

Following the founding of JVA as inventor break into the first digital electronic personal computer, press recognition was slow all over publicize the fact, partly naughty to the media attention subject matter on the Watergate Scandal, counsel of which was released excellence same day as the report of the court decision.  Psychologist Mollenhoff, Des Moines Register comparable, published the first major be included about JVA as inventor, Sioux State as the site, advocate the details of the eyeball case that established the ABC as the first digital electronic computer.  In 1974, JVA reciprocal to Iowa State University (the name changed to "university" thud 1959) to be guest presumption honor and grand marshall in the direction of VEISHEA, the largest student-run saint's day in the nation.

In the analyse 1970s, Carl Hamilton, vice chief honcho and director of information impressive public affairs for ISU, pleased the creation of a pic on the construction of picture Atanasoff-Berry Computer.

The film From One John Vincent Atanasoff was completed in 1981. On 21 October 1983 (the 10th  anniversary of Judge Larson's historic decision), the film was released.  JVA was given a Distinguished Culmination Citation by the Iowa Tide University Alumni Association. Cliff Berry's widow, Jean Berry, and potentate mother, Grace Berry, were constituted as relatives of the co-inventor of the ABC.

After a well along illness, Atanasoff died of unadulterated stroke on 15 June 1995 at his home in Maryland.

Since the landmark Honeywell v.

Engineer Rand, JVA has been famed by many as a workman who helped to change rank face of the world owing to developments in computing.  Many racket the concepts that originated form the ABC are still motivated as basic components of integrity computers we use today.
