The Analytical Engine: 28 Plans and Counting

The Analytical Engine: 28 Plans and Counting

December 10, 2015 marks the 200th anniversary of the birth of Ada Byron, later Countess of Lovelace, most famous for her 1843 description of Charles Babbage’s Analytical Engine. Beginning around 1822, English mathematician Charles Babbage designed a series of mechanical calculating machines, or as he called them Engines. Of these, the Analytical Engine is recognized today as an (unrealized) general-purpose digital computer. On the eve of the anniversary, Museum volunteer and Babbage expert, Tim Robinson, takes a look at the origins of some of the key ideas of the Analytical Engine.
