The first algorithm designed for a machine was not signed by a 20th-century engineer. It was published by Ada Lovelace in 1843, for a computer that was never even built.
Lovelace, daughter of the poet Lord Byron, translated an article about Charles Babbage's Analytical Engine and added notes that tripled the length of the original. In one of them, the famous Note G, she set out step by step how the machine could calculate a series of numbers. It is now considered the first published computer program.
But her most far-sighted idea was another: she understood that a machine like this would not have to be limited to numbers. If it could manipulate symbols, it could compose music or work with language. She wrote it a century before the first computer existed.
