Herman Hollerith 1860-1929 Invented the tabulating machine in 1890. Used electricity instead of gears to perform calculations. He dies from a heart attack in November 17, 1929
John Atanasoff 1903-1995 Clifford Berry 1918-1963 (ABC)(1939) used binary number system used in computers today. Contains 100's of vacuum tubes.
Mark 1-1944 Over 51 feet long and weighed over 5 tons, ASCC (automatic sequence controlled calculator) the first large scale automcatic digital computer
John Mauchly 1907-1980 J. Presper Eckert 1919-1995 both worked in ENIAC (electrical numerical integration and calculator) in 1946. solves mathematical faster:John Mauchly Originally a military project that was "top secret": J. Presper Eckert
Alan Turing 1912-1954 Developed idea of a universal machine in the late 30's and 40's. Called the Turing Machine. The "Enigma" he was proud ot be and wanted to defend his rights. committed suicide, he was a distant runner, Born: December 28,1903
