Augusta Ada Byron, Countess of Lovelace, was the daughter of Lord Byron and a close friend to many of the leading figures of the Victorian era; based on her report on Charles Babbage's Analytical Engine she is also generally known as the inventor of the science of computer programming. In this engrossing biography, Dorothy Stein strips away the many layers of myth to reveal a story far more dramatic and fascinating than previous accounts have indicated.

Dorothy Stein is a psychologist with a special interest in thought and language and a background in physics and computer programming. She has taught courses in nineteenth-century women's history and in the biology and psychology of sex differences, and is particularly concerned with the use of myth in science.
