Today in 1833, 192 years ago: at a high society dance in London (United Kingdom), the Scottish scientist Mary Somerville (52), tutor of London mathematician Ada Lovelace (17), introduces her to the British mathematician Charles Babbage (41). Over the next few days, Lovelace -impressed by Babbage's ideas - will visit Babbage's workshop to see his “analytical engine” (the first general-purpose mechanical computer). She will become famous for her work on this computer.
