The First Programmer


Ever given a thought , who would have been the first programmer in history of programming.

The First Programmer Was a Lady!!!!

Over a hundred years before a monstrous array of vacuum tubes surged into history in an overheated room in Pennsylvania, a properly attired Victorian Gentleman demonstrated an elegant little mechanism of wood and brass in a London drawing room. One of the ladies attending this demonstration brought along the daughter of a friend. She was a teenager with long dark hair, a talent for mathematics, and a weakness for wagering on horse races. When she took a close look at the device and realized what this older gentleman was trying to do, she surprised them all by joining him in an enterprise that might have altered history, had they succeeded.

Ada Lovelace is popularly credited as history's first programmer. She was the first to express an algorithm intended for implementation on a computer, Charles Babbage's analytical engine, in October 1842.

Analytical Engines and digital computers are very good at doing things over and over many times, very quickly. By inventing an instruction that backs up the card-reading device to a specified previous card, so that the sequence of instructions can be executed a number of times, Ada created the loop--perhaps the most fundamental procedure in every contemporary programming language.
Even thought the Engine was yet to be built, Ada experimented with writing sequences of instructions. She noted the value of several particular tricks in this new art, tricks that are still essential to modern computer languages--subroutines, loops and jumps.

Ada died of cancer at the age of thirty-six. Babbage outlived her by decades, but without Ada's advice, support, and sometimes stern guidance, he was not able to complete his long-dreamed-of Analytical Engine. Because the toolmaking art of his day was not up to the tolerance demanded by his designs.
