MOTHER
LADY BYRON was born Anne Isabel-
la “Annabella” Milbanke on May
17, 1792, the only child of wealthy,
liberal-minded parents in northern
England. Her childhood education
was first rate, and she excelled at
mathematics. During her courtship
with Lord Byron, he referred to her
as the “Princess of Parallelograms.”
Though often publicly regarded as
cold and punishing for stifling her
daughter’s creativity, Lady Byron and
Ada Lovelace appear to have had an
intellectually stimulating relationship
in adulthood, often going to Babbage’s
soirees and scientific exhibitions to-
gether. Lovelace excitedly shared her
translation and notes on the Analyt-
ical Machine with her mother. Lady
Byron was also deeply involved in
many social movements, establish-
ing cooperative schools and providing
aid to those who had escaped slavery.
