Few people change how the world thinks, but Ada Lovelace, born in 1815 in London, England, did exactly that. She is remembered for writing what many call the first computer program.
Lovelace was imaginative. She believed a calculating machine could one day work with music and pictures, not just numbers.
In 1833, Lovelace met the inventor Charles Babbage and saw his calculating machine. In 1842, Lovelace began translating an article about Babbage's planned Analytical Engine.
Later, in 1843, Lovelace published notes that included steps for the machine to calculate a series of numbers. (Algorithm: a set of step-by-step instructions for solving a problem.)
Lovelace died in 1852. A computer language, Ada, was named after her more than a century later.
