Answer:
Ada Lovelace, the Countess of Lovelace, is recognized as the world's first computer programmer. In the 19th century, she worked with Charles Babbage on his analytical engine. Lovelace's translation of an article on the engine included extensive notes, where she described a method for the engine to generate Bernoulli numbers, marking the first published computer algorithm. Her visionary insights into computing possibilities and her contributions to the analytical engine's development make her a key figure in the history of computer science. Ada Lovelace is celebrated annually on Ada Lovelace Day for her achievements in science, technology, engineering, and mathematics.
