Ada Lovelace was a mathematician.

When she was a child she loved machines and also she loved the idea of flying.

She studied birds to figure out the perfect balance between their wing size and body weight.

She tested out materials and made several designs. She never could soar like a bird,but created a book full of

pictures called 'Flyology' that had all her findings.One day she met an other mathematician named Charles Babbage and they became good friends.Together they built another machine.Ada wrote

the first computer program in history!
