Ada Lovelace NPG D5123

© National Portrait Gallery, London

by William Henry Mote, after Alfred Edward Chalon

Mathematician; the only child of the poet, Byron ('Ada! Sole daughter of my house and of my heart' - Byron's Childe Harold). Probably through the scientific writer, Mary Somerville, she met Charles Babbage, the computer pioneer. In her Sketch of the Analytical Engine, 1843, she translated from Italian and annotated an article by the Italian mathematician, General Menabrea, on Babbage's calculating machine, demonstrating her command of the principles of the programmed computer. She is sometimes described as the world's first computer programmer.
