Ada Lovelace, born Augusta Ada Byron in 1815, is widely recognized as the world's first computer programmer for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. In 1843, Lovelace translated an article about the Analytical Engine written by Italian mathematician Luigi Menabrea and added her own extensive notes, which ended up being three times longer than the original article. Within these notes, she included what is now considered the first computer algorithm—a detailed sequence of operations for the engine to calculate Bernoulli numbers. This algorithm demonstrated that the machine could be programmed to perform complex mathematical calculations, making it the first published computer program in history.

What makes Lovelace's contribution particularly remarkable is that she grasped the potential of computing far beyond mere calculation. She theorized that such machines could manipulate symbols according to rules and might one day create music or art, essentially envisioning the concept of general-purpose computing a century before modern computers existed. The Analytical Engine was never actually built during her lifetime, so her program was never tested on the actual machine, but her work laid crucial conceptual groundwork for the field of computer science. Modern programming languages and computing concepts can trace their intellectual lineage back to her pioneering insights, which is why the U.S. Department of Defense named its Ada programming language in her honor in 1980.
