Lady Ada Lovelace
1815 – 1852 · Gone at 36
The first computer programmer — a century before computers existed. Working on Charles Babbage's Analytical Engine, she wrote the first algorithm intended for machine execution. More remarkably, she foresaw that machines could compose music, generate graphics, and go far beyond pure calculation. She saw the future and wrote its first instructions.
"The Analytical Engine weaves algebraical patterns, just as the Jacquard loom weaves flowers and leaves."
