(listed on Wikipedia’s frontpage today). Babbage died before he could finish his device, but the the London Science Museum constructed a working Difference Engine ( the no. 2 design) from Babbages plans. The side shows a wood cut from a part of the difference engine 1, that was build 1833 (left image from here). When he did not succeed in building his difference engines Babbage strived for more: the analytical engine: a disign that if it ever had been realized would have been a mechanic Turing machine. The worlds first computer program was a program for the analytical engine to compute Bernoulli numbers by Ada Lovelace.
