Whose ideas laid the foundations of computing?

In the 1830s, the English mathematician Charles Babbage designed the Analytical Engine, a mechanical general-purpose computer far ahead of its time, though it was never fully built in his lifetime. His collaborator Ada Lovelace, daughter of the poet Lord Byron, wrote detailed notes on the machine, including an algorithm it could carry out — widely regarded as the first computer program. She also foresaw that such machines might one day do far more than crunch numbers, anticipating modern computing.
