The abc computer biography

This machine never saw the light of day as a serious tool for computation since it was somewhat premature in its engineering conception and limited in its logical one. Nonetheless it must be viewed as a great pioneering effort. Perhaps its chief importance was to influence the thinking of another physicist who was much interested in the computational process, John W.

During the period of Atanasoff's work on his linear equation solver, Mauchly was at Ursinus College, a small school in the environs of Philadelphia.

Somehow he became aware of Atanasoff's project and visited him for a week in During the visit the two men apparently went into Atanasoff's ideas in considerable detail. The discussion greatly influenced Mauchly and through him the entire history of electronic computers. The original ABC was eventually dismantled in[ 20 ] when the university converted the basement to classrooms, and all of its pieces except for one memory drum were discarded.

InAtanasoff again found himself in the spotlight after his work was cited in the conclusions of a patent dispute between computing-industry giants Honeywell and Sperry Rand about the early development of the digital computer. Belatedly, and largely through the advocacy of friends and writers, Atanasoff gained recognition. Owing to his father's origins, he received early plaudits in Bulgaria, where in he was granted the Order of Cyril and Methodius, First Class.

Bush for his invention of the electronic digital computer and for contributions to the development of a technically trained US workforce. Atanasoff died in The Man Who Invented the Computer is a vivid telling of the early story of the computing industry. By focusing on Atanasoff, Smiley blends obscure threads with those that are better known.

Larson found that "Eckert and Mauchly did not themselves first invent the automatic electronic digital computer, but instead derived that subject matter from one Dr.

John Vincent Atanasoff". Between andAtanasoff was a witness in the legal actions brought by various parties to invalidate electronic computing patents issued to Mauchly and J. Presper Eckertwhich were owned by computer manufacturer Sperry Rand. In the decision of Honeywell v. Sperry Randa federal judge named Atanasoff the inventor of the electronic digital computer.

Following World War II Atanasoff remained with the government and developed specialized seismographs and micro barographs for long-range explosive detection.

In he founded and led the Ordnance Engineering Corporation, selling the company to Aerojet General Corporation in and becoming Aerojet's Atlantic Division president. In Atanasoff and his wife Alice moved to their hilltop farm in New Market, Maryland for their retirement. Following the resolution of Honeywell v. Atanasoff died at the age of 91 on June 15,of a stroke at his home after a lengthy illness.

Atanasoff visited Bulgaria twice, in and He was made an honorable citizen of the town of Yambol, and received the "Key of the Town". He was also given various titles by the Bulgarian Academy of Sciences. The John Atanasov prize is awarded every year in Bulgaria.

American computer pioneer — This article needs additional citations for verification. He would use regenerative memory, which would reduce the cost of building the machine. He would compute with direct logical action rather than enumeration, which would give it increased accuracy.

To help him accomplish his goal, he hired a particularly bright electrical engineering student, Clifford E. From until they worked at developing and improving the device, later named the Atanasoff Berry Computer ABC. Near the same time, Clifford Berry accepted a defense-related job in California. Trexler, the patenting of the ABC was never completed.

He thought he would spend a few months, or at most a few years in government, and then return to Iowa State College. Lura and their three children remained in Ames, but he made frequent trips home to see his family. He was in charge of developing a computer for the United States Navy. At the same time, he became involved in the first atomic test in the Pacific, a project that he liked very much.

Neither he nor Clifford Berry had been notified that the computer was going to be destroyed. Only a few parts of the computer were saved. The long separation from his family was beginning to take its toll. He and Lura had drifted apart. In they were divorced and Lura moved with the children to Denver, Colorado. He stayed in that position until late In he established The Ordnance Engineering Corporation, a research and engineering company in Rockville, Maryland, with his old friend and student, David Beecher.

The company was sold to Aerojet General Corporation inand he became Manager of its Atlantic Division from and Vice President from
