Ada Lovelace and the Thinking Machine

Written by Studio AM.

Ada Lovelace was born in England in 1815, when women had limited access to advanced mathematical education. Her mother, however, arranged for her to study mathematics with tutors.

In 1833, Ada met Charles Babbage and saw a demonstration of part of his Difference Engine, a mechanical calculating device. Babbage later developed plans for the more ambitious Analytical Engine. Unlike a machine designed for one fixed kind of calculation, it would follow instructions for different tasks. It was never fully built in his lifetime.

In 1843, Ada translated an article about the Analytical Engine from French. She did far more than translate it. She added detailed notes, including a procedure for calculating a sequence called Bernoulli numbers. The notes contain an early published example of instructions intended for a general-purpose computing machine.

The notes also stress a broader idea. If numbers could stand for other things, she reasoned, the engine might work with more than quantities. She discussed the possibility of representing musical relationships and composing music. Her contribution was not a machine she built, but an account of what a programmable machine might do. She died at thirty-six, long before such a machine became a practical reality. Her published notes remain an important part of computing history.
