In this kids' biography, discover the inspiring story of Ada Lovelace, who wrote the world's first computer program. In 1833, Ada Lovelace met mathematician Charles Babbage, inventor of calculating machines. She went on to devise a way of inputting data into Babbage's Analytical Machine, and in doing so became the first-ever computer programmer. In this kids' biography book for 8-11 year olds, learn all about Ada Lovelace's fascinating life, including her famous father (celebrated poet Lord Byron), her talent for languages and mathematics, and her predictions for how computers could change our lives.
