Happy Lady Ada Day!
Ada Lovelace was one of the world’s first computer programmers, and one of the first people to see computers as more than just a machine for doing sums. She wrote programmes for Charles Babbage’s Analytical Engine, a general-purpose computing machine, despite the fact that it was never built. She also wrote the very first description of a computer and of software.
