![]() ![]() According to a 1999 Scientific American article written by Eugene Eric Kim and Betty Alexandra Toole, “many modern computer pioneers eventually became aware of Babbage’s work and of Ada’s paper, but all of them made their conceptual breakthroughs independently.” The first modern computers used punched cards, too, but, according to some scholars, the Analytical Engine did not influence their development. A major innovation of this machine, which was designed by Charles Babbage but never built, was that it used punched cards to automate complicated calculations. The machine was called the Analytical Engine. So who was Ada Lovelace, and why is she the STEM poster-woman?Ī mathematician by education, Lovelace made her mark through a series of notes she published in 1843 concerning designs for what could have been the world’s first computer. ![]() On the second Tuesday of October, scientists, feminists, and computer enthusiasts across the globe celebrate Ada Lovelace Day, an international fête created in 2009 by Suw Charman-Anderson to recognize women in STEM fields (science, technology, engineering, and math). ![]()
