Human computers were involved in calculating ballistics tables during World War I. [38] Between the two world wars, computers were used in the Department of Agriculture in the United States and also at Iowa State College. [39] The human computers in these places also used calculating machines and early electrical computers to aid in their work ...
Before the 1920s, computers (sometimes computors) were human clerks that performed computations. They were usually under the lead of a physicist. Many thousands of computers were employed in commerce, government, and research establishments. Many of these clerks who served as human computers were women.
The smallest general-purpose computers were the B700 "microprocessors" which were used both as stand-alone systems and as special-purpose data-communications or disk-subsystem controllers. Burroughs manufactured an extensive range of accounting machines including stand-alone systems such as the Sensimatic , L500 and B80 and dedicated terminals ...
Mark Dean, an African-American computer scientist and engineer, spent over 30 years at IBM pursuing the Next Big Thing. He was chief engineer of the 12-person team that designed the original IBM ...

These machines were never actually built, as they were more of a thought experiment to produce new knowledge in systematic ways; although they could make simple logical operations, they still needed a human being for the interpretation of results. Moreover, they lacked a versatile architecture, each machine serving only very concrete purposes.
American engineer Peter Cooper Hewitt invented the Fluorescent lamp. 1904: English engineer John Ambrose Fleming invented the diode. 1906: American inventor Lee de Forest invented the triode. 1908: Scottish engineer Alan Archibald Campbell-Swinton, laid out the principles of television. 1909: Mica capacitor was invented by William Dubilier. 1911
ENIAC (/ ˈ ɛ n i æ k /; Electronic Numerical Integrator and Computer) [1] [2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [3] [4] Other computers had some of these features, but ENIAC was the first to have them all.
