KONRAD ZUSE
First freely programmable computer. was a German civil engineer, inventor and computer pioneer. His greatest achievement was the world's first programmable computer; the functional program-controlled Turing-complete Z3 became operational in May 1941. Thanks to this machine and its predecessors, Zuse has often been regarded as the inventor of the modern computer.[2][3][4][5][6][7] Zuse was also noted for the S2 computing machine, considered the first process-controlled computer. He founded one o -
John Atanasoff & Clifford Berry
Who was first in the computing biz is not always as easy as ABC. was the first automatic electronic digital computer, an early electronic digital computing device that has remained somewhat obscure. The ABC's priority is debated among historians of computer technology, because it was not programmable, nor Turing-complete.[1] Many credit John Mauchly and J. Presper Eckert, creators of the ENIAC,[2] which came into use in July 1946, with the title. Others cite the programmable British Colossus com -
Howard Aiken & Grace Hopper
The Harvard Mark 1 computer.Aiken studied at the University of Wisconsin–Madison and later obtained his PhD in physics at Harvard University in 1939.[2][3] During this time, he encountered differential equations that he could only solve numerically. He envisioned an electro-mechanical computing device that could do much of the tedious work for him. This computer was originally called the ASCC (Automatic Sequence Controlled Calculator) and later renamed Harvard Mark I. With engineering, construc -
John Presper Eckert & John W. Mauchly
was an American electrical engineer and computer pioneer. With John Mauchly he invented the first general-purpose electronic digital computer (ENIAC), presented the first course in computing topics (the Moore School Lectures), founded the Eckert–Mauchly Computer Corporation, and designed the first commercial computer in the U.S., the UNIVAC, which incorporated Eckert's invention of the mercury delay line memory. -
John Bardeen, Walter Brattain & Wiliam Shockley
was an American physicist and inventor. Shockley was the manager of a research group that included John Bardeen and Walter Houser Brattain, the duo who invented the transistor. The three were jointly awarded the 1956 Nobel Prize in Physics. Shockley's attempts to commercialize a new transistor design in the 1950s and 1960s led to California's "Silicon Valley" becoming a hotbed of electronics innovation. In his later life, Shockley was a professor at Stanford and became a proponent of eugenics.[ -
Frederic Williams & Tom Kilburn
In 1946 he was appointed as head of the Electrical Engineering Department of the University of Manchester. There, with Tom Kilburn, he pioneered the first stored-program digital computer, the Manchester Mark 1 computer -

International Business Machines
e generic term "personal computer" was in use before 1981, applied as early as 1972 to the Xerox PARC's Alto, but because of the success of the IBM Personal Computer, the term "PC" came to mean more specifically a desktop microcomputer compatible with IBM's PC products. Within a short time of the introduction, third-party suppliers of peripheral devices, expansion cards, and software proliferated; the influence of the IBM PC on the personal computer market was substantial in standardizing a plat
