In 1967 Honeywell sued Sperry Rand in an attempt to break their ENIAC patents, arguing the ABC constituted prior art.

The United States District Court for the District of Minnesota released its judgement on October 19, 1973, finding in Honeywell v. Sperry Rand that the ENIAC patent was a derivative of John Atanasoff's invention.

The six computer manufacturers were Burroughs Corporation, IBM, Minneapolis-Honeywell ( Honeywell Labs ), RCA, Sperry Rand, and Sylvania Electric Products.

The ABC was largely forgotten until it became the focus of the lawsuit Honeywell v. Sperry Rand, the ruling of which invalidated the ENIAC patent ( and several others ) as, among many reasons, having been anticipated by Atanasoff's work.

RCA was one of several major computer companies ( see also: Computing ) that also included IBM, Digital Equipment Corporation, Burroughs, Control Data Corporation, General Electric, Honeywell, NCR and Sperry Rand through most of the 1960s.

* November 11 – Sperry Rand and Burroughs merge to form Unisys, becoming the second largest computer company.

Rand soon merged with Sperry Corporation to become Sperry Rand.

Groves went on to become a vice-president at Sperry Rand.

Groves went on to become a vice president at Sperry Rand, an equipment and electronics firm.

He retired from Sperry Rand in 1961.

For a variety of reasons ( including Mauchly's June 1941 examination of the Atanasoff – Berry Computer, prototyped in 1939 by John Atanasoff and Clifford Berry ), US patent 3, 120, 606 for ENIAC, granted in 1964, was voided by the 1973 decision of the landmark federal court case Honeywell v. Sperry Rand, putting the invention of the electronic digital computer in the public domain and providing legal recognition to Atanasoff as the inventor of the first electronic digital computer.

However, in 1955 Remington merged with Sperry Corporation to become Sperry Rand.

Atansoff invented the first digital computer in the world during the 1930s in the Iowa State College, but it took a lengthy court battle for achieving legal patent to 1973 when the case of Honeywell v. Sperry Rand was solved and the verdict named Atansoff with the title the inventor of the computer, the decision was never appealed, thus giving him the legal right to be called as such in the United States.

: For a more detailed account, see Honeywell v. Sperry Rand.

Between 1954 and 1973, Atanasoff was a witness in the legal actions brought by various parties to invalidate electronic computing patents issued to John Mauchly and J. Presper Eckert, which were owned by computer manufacturer Sperry Rand.

In the 1973 decision of Honeywell v. Sperry Rand, a federal judge named Atanasoff the inventor of the electronic digital computer.

Atanasoff agreed to assist the attorney, but IBM ultimately entered a patent-sharing agreement with Sperry Rand, the owners of the Eckert-Mauchly memory patent, and the case was dropped.

Atanasoff was deposed and testified at trial in the later action Honeywell v. Sperry Rand.

They took possession of the island at the expiration of Sperry Rand's lease in 1963.

The following day, several thousand strikers, families and sympathizers took part in a funeral procession down Market Street, stretching more than a mile and a half, for Nicholas Bordois and Howard Sperry, the two persons killed on " Bloody Thursday ".

CBI's Burroughs Corporation Records includes over 100, 000 photographs depicting the entire visual history of Burroughs from its origin as the American Arithmometer Corporation in 1886 to its merger with the Sperry Corporation to form the Unisys Corporation in 1986.

When Sperry was given money to persuade him to rebuild his factory in the village, he handed it over to the village trustees with the instructions that it be given to the fire department to help in the purchase of a new booster pump.

In 1918 Lawrence Sperry split from his father to compete over aero-instruments with the Lawrence Sperry Aircraft Company, including the new automatic pilot.

After setting up eight companies and taking out over 400 patents, Sperry died in Brooklyn on 16 June 1930.

Sperry has also competed in mixed martial arts, with wins over such fighters as Vernon White and Igor Vovchanchyn.

Zinoviev was a feared Russian kickboxer and sambo specialist who held wins over Mario Sperry and Enson Inoue.

Wins over Mario Sperry, Akira Shoji and Alexander Otsuka established him as a respectable contender in the organization.

The new Sperry and Perry Hotel was considered one of the finest hotels outside of San Francisco, and was host to many famous people over the years.

Shrinking demand and tough competition started a shakeout in the market in the early 1970s — RCA sold out to UNIVAC and GE also left ; in the 1980s Honeywell was bought out by Bull ; UNIVAC became a division of Sperry, which later merged with Burroughs to form Unisys Corporation in 1986.

Sperry bought out and continued the RCA line of electronic digital computers: architectural cousins to the IBM System / 360.

RCA originally called this operating system Time Sharing Operating System ( TSOS ), running on RCA's Spectra 70 line of virtual memory systems and changed its name to VMOS before the Sperry acquisition of RCA CSD.

After RCA decided to get out of the computer business due to stunning losses, it sold most of its computer and peripheral lines to Sperry ; a few were sold to Singer Corporation.

Until 1994 the base also operated a Type 80 radar and a Sperry TPS-34 amongst others.

On returning to the United States in January 1918, he visited Sperry Gyroscope and Ford Instruments to consult with them on fire control systems.

The UNIVAC 1110 was the fourth member of Sperry Rand's UNIVAC 1100 series of computers, introduced in 1972.

Today automated flight control is common to reduce pilot error and workload at key times like landing or takeoff. Autopilot was first invented by Lawrence Sperry during World War II to fly bomber planes steady enough to hit precision targets from 25, 000 feet.

In 1947 the Navy contracted Sperry to build a beam riding version of a standard HVAR, the standard unguided aerial rocket, under Project Hotshot.

The company was founded in 1886 as the American Arithmometer Company and after the 1986 merger with Sperry Univac was renamed as Unisys.

In September 1986, Burroughs Corporation merged with Sperry Corporation to form Unisys.

In 1916, Lawrence Sperry patented and built an " aerial torpedo ", a small biplane carrying a TNT charge, a Sperry autopilot and a barometric altitude control.

* 1975 — Sperry Univac Introduce MAPPER ( MAintain, Prepare, and Produce Executive Reports ) is a database management and reporting system that includes the world's first 4GL.

* 1983 — Sperry Corporation Martyn Richard Jones defines the Sperry Information Center approach, which while not being a true DW in the Inmon sense, did contain many of the characteristics of DW structures and process as defined previously by Inmon, and later by Devlin.

One example is the MAPPER system developed by Sperry.

He also has the lead role in Christiano's film The Secrets of Jonathan Sperry.

The latter architecture has continued to evolve into their current zSeries mainframes which, along with the then Burroughs and Sperry ( now Unisys ) MCP-based and OS1100 mainframes, are among the few mainframe architectures still extant that can trace their roots to this early period.
