Samuel Lubkin
Samuel Lubkin (1906-1972) was a mathematician and computer scientist instrumental in the early history of computing. Life Lubkin studied mathematics at Cooper Union in New York City, and was president of the Cooper Union Mathematics Club in the 1923-1924 academic year. He received a PhD in applied mathematics from Courant Institute of Mathematical Sciences. He later went on to work on the design of the ENIAC computer while at the Moore School of Electrical Engineering at the University of Pennsylvania. Lubkin afterwards joined the US Army's Ballistic Research Laboratory to work with other ENIAC designers on the design of the EDVAC computer's programming system, It has been claimed that the "Operating Manual for the EDVAC", which was authored by Lubkin, was "the bible of the computer industry in the late 1940s and early 1950s". After that he joined the design team who went on to build the first UNIVAC computer. In the 1940s, Reeves Instrument Corporation hired Lubkin to lead a pr ...

UNIVAC
UNIVAC (Universal Automatic Computer) was a line of electronic digital stored-program computers starting with the products of the Eckert–Mauchly Computer Corporation. Later the name was applied to a division of the Remington Rand company and successor organizations. The BINAC, built by the Eckert–Mauchly Computer Corporation, was the first general-purpose computer for commercial use, but it was not a success. The last UNIVAC-badged computer was produced in 1986. History and structure J. Presper Eckert and John Mauchly built the ENIAC (Electronic Numerical Integrator and Computer) at the University of Pennsylvania's Moore School of Electrical Engineering between 1943 and 1946. A 1946 patent rights dispute with the university led Eckert and Mauchly to depart the Moore School to form the Electronic Control Company, later renamed Eckert–Mauchly Computer Corporation (EMCC), based in Philadelphia, Pennsylvania. That company first built a computer called BINAC (BINar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic Tape Data Storage
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording. Tape was an important medium for primary data storage in early computers, typically using large open reels of IBM 7 track, 7-track, later 9-track tape, 9-track tape. Modern magnetic tape is most commonly packaged in cartridges and cassettes, such as the widely supported Linear Tape-Open (LTO) and IBM 3592 series. The device that performs the writing or reading of data is called a tape drive. Autoloader (data storage device), Autoloaders and tape library, tape libraries are often used to automate cartridge handling and exchange. Compatibility was important to enable transferring data. Tape data storage is now used more for system backup, data archive and data exchange. The low cost of tape has kept it viable for long-term storage and archive. Open reels Initially, magnetic tape for data storage was wound on reels. This standard for large computer systems persis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drum Memory
Drum memory was a magnetic data storage device invented by Gustav Tauschek in 1932 in Austria. Drums were widely used in the 1950s and into the 1960s as computer memory. For many early computers, drum memory formed the main working memory of the computer. It was so common that these computers were often referred to as ''drum machines''. Some drums were also used as secondary storage as for example various IBM drum storage drives. Drums were displaced as primary computer memory by magnetic core memory, which offered a better balance of size, speed, cost, reliability and potential for further improvements. Drums in turn were replaced by hard disk drives for secondary storage, which were both less expensive and offered denser storage. The manufacturing of drums ceased in the 1970s. Technical design A drum memory or drum storage unit contained a large metal cylinder, coated on the outside surface with a ferromagnetic recording material. It could be considered the precu ...

Vacuum Tube Computer
A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. Although superseded by second-generation transistorized computers, vacuum-tube computers continued to be built into the 1960s. These computers were mostly one-of-a-kind designs. Development The use of cross-coupled vacuum-tube amplifiers to produce a train of pulses was described by Eccles and Jordan in 1918. This circuit became the basis of the flip-flop, a circuit with two states that became the fundamental element of electronic binary digital computers. The Atanasoff–Berry computer, a prototype of which was first demonstrated in 1939, is now credited as the first vacuum-tube computer. However, it was not a general-purpose computer, being able to only solve a system of linear equations, and was also not very reliable. During World War II, special-purpose vacuum-tube digital computers such as Colossus were used to break German machine (teleprinter) ...

Evelyn Berezin
Evelyn Berezin (April 12, 1925 – December 8, 2018) was an American computer designer of the first computer-driven word processor. She also worked on computer-controlled systems for airline reservations. Early life and education Berezin was born in the east Bronx in 1925 to Jewish immigrants from the Russian Empire, and attended Christopher Columbus High School. She started university at the age of sixteen at Hunter College in January 1941, studying Economics instead of the Physics she preferred because it was preferred as a subject for women at that time. After WWII started, new opportunities made the study of physics possible with a scholarship at New York University, plus free classes at both Hunter and Brooklyn Polytech during the war years. At the same time, she worked full-time during the day as an assistant in the Rheology Department of the Research Division of the International Printing Company (IPI). Going to university at night, she received her B.S. in physics i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Un-American Activities Committee
The House Committee on Un-American Activities (HCUA), popularly dubbed the House Un-American Activities Committee (HUAC), was an investigative committee of the United States House of Representatives, created in 1938 to investigate alleged disloyalty and subversive activities on the part of private citizens, public employees, and those organizations suspected of having either fascist or communist ties. It became a standing (permanent) committee in 1945, and from 1969 onwards it was known as the House Committee on Internal Security. When the House abolished the committee in 1975, its functions were transferred to the House Judiciary Committee. The committee's anti-communist investigations are often associated with McCarthyism, although Joseph McCarthy himself (as a U.S. Senator) had no direct involvement with the House committee. McCarthy was the chairman of the Government Operations Committee and its Permanent Subcommittee on Investigations of the U.S. Senate, not the House. ...

Eckert–Mauchly Computer Corporation
The Eckert–Mauchly Computer Corporation (EMCC) (March 1946 – 1950) was founded by J. Presper Eckert and John Mauchly. It was incorporated on December 22, 1947. After building the ENIAC at the University of Pennsylvania, Eckert and Mauchly formed EMCC to build new computer designs for commercial and military applications. The company was initially called the Electronic Control Company, changing its name to Eckert–Mauchly Computer Corporation when it was incorporated. In 1950, the company was sold to Remington Rand, which later merged with Sperry Corporation to become Sperry Rand, and survives today as Unisys. Founding Before founding Eckert–Mauchly Computer Corporation, Mauchly researched the computing needs of potential clients. Over a period of six months in 1944 he prepared memos and kept detailed notes of his conversations. For instance, Mauchly met with United States Census Bureau official William Madow to discuss the computing equipment they desired. The Ce ...

SEAC (computer)
SEAC (''Standards Eastern Automatic Computer'' or ''Standards Electronic Automatic Computer'') was a first-generation electronic computer, built in 1950 by the U.S. National Bureau of Standards (NBS) and was initially called the ''National Bureau of Standards Interim Computer'', because it was a small-scale computer designed to be built quickly and put into operation while the NBS waited for more powerful computers to be completed (the DYSEAC). The team that developed SEAC was organized by Samuel N. Alexander. SEAC was demonstrated in April 1950 and was dedicated on June 1950; it is claimed to be the first fully operational stored-program electronic computer in the US. Description Based on EDVAC, SEAC used only 747 vacuum tubes (a small number for the time) eventually expanded to 1,500 tubes. It had 10,500 germanium diodes which performed all of the logic functions (see the article diode–transistor logic for the working principles of diode logic), later expanded to 16,000 ...
