She was the eighteen-year-old daughter of the poet Lord Byron and Lady Annabella Byron, whose marriage had disintegrated in Ada''s youth. Through thoughtful narrative accompanied by direct quotes, readers will learn how in Babbage''s plans for the Analytical Engine and Lovelace''s algorithm lies the foundation of the computer hardware and software that would not be developed for another hundred plus years.
