The First Programmer

Augusta Ada Byron was born on December 10, 1815, in London, the only legitimate child of Lord Byron and Anne Isabella Milbanke. Her parents separated when she was a month old. Byron died when Ada was eight. Her mother pushed her toward mathematics -- unusual for a woman in early 19th-century England.

At 17, Ada met Charles Babbage, who had designed the Analytical Engine -- a programmable mechanical computer using punch cards. Never built, it was the first general-purpose computer on paper. In 1842, Luigi Menabrea published a paper on it in French. Ada translated it and added notes three times longer than the original.

In those 1843 notes, she outlined an algorithm for computing Bernoulli numbers -- considered the first computer program. It included loops, conditional branching, and step-by-step notation foreshadowing modern programming languages. But she went further. She imagined the machine could manipulate symbols, not just numbers. If music or language could be represented symbolically, the machine could process them. Most people saw a fancy calculator. Ada saw a universal tool.

Ada died in 1852 at 36. Her notes were forgotten until computing became reality in the mid-20th century. In 1980, the U.S. Department of Defense named a programming language Ada in her honor. She didn't build a computer. She described what computing could be -- a century before it existed. The program ran in her mind, on paper, in an imagined future. When that future arrived, her vision was already there.
