1832 MECHENICAL CALCULATOR__ADA
AUGUSTA LOVELACE...

While in her late twenties, Ada Lovelace (1851-1852), the daughter of the poet Lord Byron, became involved with work on Babbage's analytical engine. Among her many contributions,she suggested using the machine's ability to jump from one set of punched cards to another if certain conditions were met. This meant separate sets of cards would not have to be prepared each time the same calculating process was reused.

When a process was to be repeated,the machine would "jump" to the necessary set of cards and use them. This is the priciple behind the contemporary programmer's use of loops and subroutines. Working with Babbage, Lovelace also designed a program to computer Bermoulli numbers on the machine. Because of these contributions to the development of computers, Lovelace is considered the first programming language, Ada, was named after her.
