Ada Loveless, English Mathematician (1815-1852)

Published the first algorithm.  Daughter of Lady Byron, she translated from French a military Analytical Engine.  Many historians regard her accompanying notes to be the first computer algorithm, although her contemporary, Charles Babbage, is also credited with that.  Loveless, however, expanded how the Analytical Engine could do something beyond calculating numbers, such as composing musical harmonies or “operating notations” of symbols.

This was the first fully-automatic calculating machine. British computing pioneer Charles Babbage (1791-1871) first conceived the idea of an advanced calculating machine to calculate and print mathematical tables in 1812. This machine, conceived by Babbage in 1834, was designed to evaluate any mathematical formula and to have even higher powers of analysis than his original Difference engine of the 1820s. Only part of the machine was completed before his death in 1871. This is a portion of the mill with a printing mechanism. Babbage was also a reformer, mathematician, philosopher, inventor and political economist.
