Ada Lovelace
Pioneering computer programmer Ada Lovelace (1815-1852) was known by Charles Babbage, Lucasian Professor of Mathematics at the University of Cambridge, UK as the “enchantress of numbers”. During her life she had significant correspondence with Babbage, extending his notes and ideas on The Analytical Machine, which is considered as the world's first programmable computer. Lovelace’s contribution paved they way for computers to be viewed as more than just calculators, in that they could also for example compose music. Lovelace therefore is the GrandMama of the Sentimental Machine.
