Richard Milton Bloch
Richard Milton Bloch (1921 – 2000) was a pioneering American computer programmer. Bloch, Grace Hopper, and Robert Campbell were the first programmers of the Harvard Mark I, an electromechanical computer which, when it began operation in 1944, was the first American programmable computer. Early life Bloch was born in Rochester, New York, on June 18, 1921, and grew up there, being graduated from Benjamin Franklin High School. He then attended Harvard University on a scholarship, majoring in mathematics, being graduated in 1943. He then immediately joined the Navy, as World War II was in progress, and was assigned to the United States Naval Research Laboratory, Naval Research Institute. There, he was recruited by Howard Aiken to work on the Mark I project, moving to Harvard in March 1944. Mark I work The Harvard Mark I became operational in 1944, and was used for war work, including computation of ballistic tables, Bessel function, Bessel tables for electronics and other applicat ...

Grace Hopper
Grace Brewster Hopper (; December 9, 1906 – January 1, 1992) was an American computer scientist, mathematician, and United States Navy Rear admiral (United States), rear admiral. One of the first programmers of the Harvard Mark I, Harvard Mark I computer, she was a pioneer of computer programming who invented one of the first Linker (computing), linkers. Hopper was the first to devise the theory of machine-independent programming languages, and the FLOW-MATIC programming language she created using this theory was later extended to create COBOL, an early high-level programming language still in use today. Prior to joining the Navy, Hopper earned a Ph.D. in mathematics from Yale University and was a professor of mathematics at Vassar College. Hopper attempted to enlist in the Navy during World War II but was rejected because she was 34 years old. She instead joined the Navy Reserves. Hopper began her computing career in 1944 when she worked on the Harvard Mark I team led by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subroutine
In computer programming, a function or subroutine is a sequence of program instructions that performs a specific task, packaged as a unit. This unit can then be used in programs wherever that particular task should be performed. Functions may be defined within programs, or separately in libraries that can be used by many programs. In different programming languages, a function may be called a routine, subprogram, subroutine, method, or procedure. Technically, these terms all have different definitions, and the nomenclature varies from language to language. The generic umbrella term ''callable unit'' is sometimes used. A function is often coded so that it can be started several times and from several places during one execution of the program, including from other functions, and then branch back (''return'') to the next instruction after the ''call'', once the function's task is done. The idea of a subroutine was initially conceived by John Mauchly during his work on ENIAC, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Meiko Scientific
Meiko Scientific Ltd. was a British supercomputer company based in Bristol, founded by members of the design team working on the Inmos transputer microprocessor. History In 1985, when Inmos management suggested the release of the transputer be delayed, Miles Chesney, David Alden, Eric Barton, Roy Bottomley, James Cownie, and Gerry Talbot resigned and formed Meiko (Japanese for "well-engineered") to start work on massively parallel machines based on the processor. Nine weeks later in July 1985, they demonstrated a transputer system based on experimental 16-bit transputers at the SIGGRAPH in San Francisco. In 1986, a system based on 32-bit T414 transputers was launched as the ''Meiko Computing Surface''. By 1990, Meiko had sold more than 300 systems and grown to 125 employees. In 1993, Meiko launched the second-generation ''Meiko CS-2'' system, but Meiko ran into financial difficulties in the mid-1990s. The Meiko technical team and technology was transferred to a joint venture co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric
General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and headquartered in Boston. The company operated in sectors including healthcare, aviation, power, renewable energy, digital industry, additive manufacturing and venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company announced it would divide itself into three investment-grade public companies. On July 18, 2022, GE unveiled the brand names of the companies it will ...

RAYDAC
The RAYDAC (for Raytheon Digital Automatic Computer) was a one-of-a-kind computer built by Raytheon. It was started in 1949 and finished in 1953. It was installed at the Naval Air Missile Test Center at Point Mugu, California. The RAYDAC used 5,200 vacuum tubes and 18,000 crystal diodes. It had 1,152 words of memory (36 bits per word), using delay-line memory, with an access time of up to 305 microseconds. Its addition time was 38 microseconds, multiplication time was 240 microseconds, and division time was 375 microseconds. (These times exclude the memory-access time.) See also * List of vacuum-tube computers Vacuum-tube computers, now called first-generation computers, are programmable digital computers using vacuum-tube logic circuitry. They were preceded by systems using electromechanical relays and followed by systems built from discrete transis ...
