"A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian,[1] which is used as an amplifier for high radio frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power klystrons are used as output tubes in UHF television transmitters, satellite communication, radar transmitters, and to generate the drive power for modern particle accelerators."

"The company was incorporated on April 14 1910 by Elmer Ambrose Sperry as the Sperry Gyroscope Company, to manufacture navigation equipment—chiefly his own inventions: the marine gyrostabilizer and the gyrocompass—at 40 Flatbush Avenue Extension in Downtown Brooklyn. During World War I the company diversified into aircraft components including bomb sights and fire control systems. 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 the death of Lawrence on December 13, 1923, the two firms were brought together in 1924. Then in January 1929 it was acquired by North American Aviation, who reincorporated it in New York as the Sperry Gyroscope Company, Inc. The company once again became independent in 1933 when it was spun-off as a subsidiary of the newly formed Sperry Corporation. The new corporation was a holding company for a number of smaller entities such as the original Sperry Gyroscope, Ford Instrument Company, Intercontinental Aviation, Inc., and others. The company made advanced aircraft navigation equipment for the market, including the Sperry Gyroscope and the Sperry Radio Direction Finder. It also moved into the hydraulics industry when it acquired Vickers, Inc. in 1937. Sperry supported the work of a group of Stanford University inventors, led by Russell and Sigurd Varian, who had invented the klystron, and incorporated this technology and related inventions into their products. The company prospered during World War II as military demand skyrocketed, ranking 19th among US corporations in the value of wartime production contracts. It specialized in high technology devices such as analog computer–controlled bomb sights, airborne radar systems, and automated take-off and landing systems. Sperry also was the creator of the Ball Turret Gun mounted under the Boeing B-17 Flying Fortress and the Consolidated B-24 Liberator. Postwar, Sperry expanded its interests in electronics and computing, producing the company's first digital computer, SPEEDAC, in 1953. During the 1950s, a large part of Sperry Gyroscope moved to Phoenix, Arizona and soon became the Sperry Flight Systems Company. In 1955, Sperry acquired Remington Rand and renamed itself Sperry Rand. Acquiring then- Eckert–Mauchly Computer Corporation and Engineering Research Associates along with Remington Rand, the company developed the successful UNIVAC computer series and signed a valuable cross-licensing deal with IBM. In 1977, Sperry Rand purchased Varian Data Machines so as to enter the minicomputer market. In 1978, Sperry Rand decided to concentrate on its computing interests, and sold a number of divisions including Remington Rand Systems, Remington Rand Machines, Ford Instrument Company and Sperry Vickers. The company dropped "Rand" from its title and reverted to Sperry Corporation. On September 16, 1986, after the success of a second hostile takeover bid engineered by Burroughs Corporation CEO and former U.S. Secretary of the Treasury, Michael Blumenthal, Sperry Corporation merged with Burroughs Corporation. The newly merged company was renamed Unisys Corporation— a portmanteau of "united", "information", and "systems," while also referencing Sperry's well-known previous UNIVAC computer branding. The name Sperry lives on in the company Sperry Marine, headquartered in New Malden, England. This company, formed in 1997, from three well-known brand names in the marine industry—Sperry Marine, Decca, and C. Plath—is now part of Northrop Grumman Corporation. It is a worldwide supplier of navigation, communication, information and automation systems for commercial marine and naval markets." (Source: Wikipedia)
