## Mathematician

English mathematician and writer, chiefly known for her work on Charles Babbage's Analytical Engine.

Creator of the first algorithm intended to be carried out by a machine.

Hence she is often regarded as the first computer programmer.

## Notable Quotes

*Many persons who are not conversant with mathematical studies imagine that because the business of [Babbage's Analytical Engine] is to give its results in numerical notation, the nature of its processes must consequently be arithmetical and numerical, rather than algebraical and analytical. This is an error. The engine can arrange and combine its numerical quantities exactly as if they were letters or any other general symbols; and in fact it might bring out its results in algebraic notation, were provisions made accordingly.*- -- $1844$ (quoted in 1997: Donald E. Knuth:
