Ada Lovelace

, born Augusta Ada Byron and later known as Countess of Lovelace or Lady King after her husband, (AUDIO: The Enchantress of Numbers) was the daughter of Lord George Gordon Byron and his wife Annabella.

Weeks before leaving for Switzerland in 1816, Byron abandoned her and her mother. (AUDIO: The Witch from the Well) The Star Chamber recruited her at a young age through her mother, and they had her raised separate from her father's influence so that her mind would be applied to science rather than poetry. (PROSE: The Book of the War) Her parentage by Lord Byron was in fact generally kept secret. According to Colonel Wildman, Ada's distaste for her father came entirely from her mother's influence.

As a mathematics prodigy, she struggled to understand the Musical Offering but found immediate value in Charles Babbage's analytical engine, with which she developed a plan for invading the Eleven-Day Empire, which was put into practice in the Clockwork Ouroboros affair in 1834. (PROSE: The Book of the War) This was the world's first computer program. (AUDIO: The Enchantress of Numbers)

As one of England's foremost mathematicians and logicians, Lovelace was given the epithet the "Enchantress of Numbers". She considered herself to be an analyst and a metaphysician. Lovelace also invented poetical science.

By 1852, Lovelace considered her life with mathematics to be behind her. She preferred to play cards with Colonel Wildman at Newstead Abbey. Lovelace repeatedly refused Edvard Scheutz's efforts to gain her assistance with his calculation engine.

Prior to first meeting her, the Fourth Doctor had read all of Lovelace's notes on Babbage's Analytical Engine, and found them remarkable. (AUDIO: The Enchantress of Numbers)
