Tech Timeline

 Computers originated from telephone switches in the early 1900s with the switch position meaning 1 for on and 0 for off. Computers built in 1940s had thousands of switches occupied entire rooms. The early computers were largely used for military purpose for codebreaking and calculating the paths of bombs in World War II. Thanks to the Moores Law those large switches reduced size by by half every two years. In the 1970s an entire computer could fit on one coin-sized device known as a computer chip. A 1940 room sized computer could fit on a chip smaller than a pinhead. 

• (1752-1834) Joseph Marie Jacquard Influenced modern programmable devices IBM digital complier.
• (1791-1871) Charles Babbage British mathematician aka "father of the computer" first automatic mechanical computer.
• (1815-1852) Ada Lovelace known as the first computer programmer.
• (1860-1929) Herman Hollerith Creator of the punch card tabulating machine. Which was electromechanical computer used to summarize data stored on punched cards. Also invented the keypunch machine to create the punch cards.
• (1912-1954) Alan Turing Cryptologic methods during World War II. Electromechanical crytanalytic machine called the bomb decipher that intercepted the German messages and helping the Allies win the war. 
• (1906-1992) Grace Hopper she began work on the universal automatic compiler (UNIVAC) project and helped develop the UNIVAC I computer.
