In the middle of the 19th century, Ada Lovelace, who was a mathematician turned computer scientist, aided Charles Babbage in developing the first computer algorithm, which ushered in the computer age, leading to machines capable of executing functions far more rapidly than could any possible human and resulting in every subsequent development in the field, from the development of the very first personal computer nearly a century later to the programs that today sequence genomes.
