In the book The Story of Mathematics, I learned a bit about the world's first computer program. Though the Analytical Engine of Charles Babbage was never built, there was a person who worked closely with Babbage, and who was able to design instructions for calculating Bernoulli numbers using the theoretical machine. This is considered to be the world's first computer program, even though it was never implemented. That person's name was Augusta Ada King, also known as Ada Lovelace.
Yup, that's right. The world's first programmer was none other than... a woman.
