Balise Pascal was one of the most respected mathematician and physicist of his time period. Pascal was eighteen whenn he invented numerical wheel calculator called the Pascaline.

Difference Engine

Jan 1, 1786

A difference engine is an automatic mechanical calculator designed to solve polnomial functions, and it can compute many sets of numbers.

Charles Babbage

Jan 1, 1820

In the time period of 1820s babbage worked on his "Different Engine" a machine that could perform mathematical calculations. He then devolped plans for a bigger and hopefully better machine "Different Engine 2"

Ada Lovelace

Jan 1, 1833

Ada had in 1833 when she was seventeen and when babbage introduced the small working section of the engine.

Census Counting Machine

Mark II

Jan 1, 1947

The "Harvard Mark II" was an electromechanical computer built at Harvard University and was finished in 1947. It was constructed with high-speed electromagnetic relays, were put in instead of electro-mechanical counters used in the first computer know as "Mark I"

Basic

Jan 1, 1964

In 1964 John G Kenmy and Thomas E Kurtz had designed the original BASIC language. They wanted to allow students in other things besides science.

Herman Hollerith

Jan 1, 1970

http://inventors.about.com/library/inventors/blhollerith.htm Herman Hollerith invented the computer punch cards. Hollerith's punch cards and machines were a step toward automated computation. His device could automatically read information which had been punched onto card. And the computer punch cards weren't used in computers until the last 1970s
