Ada Lovelace was a collaborator with Babbage, Charles in the 18th Century, and daughter of the poet Lord Byron. She is regarded as the first programmer, designing algorithsm that would run on the Analytical Engine,.
Critically also she was an early philosopher of computation, identifiying the mportance of symbolic results and difference between calcuation and computation:
"The Difference Engine can merely tabulate, and is incapable of developing, the Analytical Engine can either tabulate or develope"
She also wrpte in aesthetic terms appreciating the "intrinsic beauty, symmetry and logical completeness<\em>" of mathemtatcal sciences and the way that the Analytical Engine "weaves algebraical patterns just as the Jacquard loom weaves flowers and leaves".
