Charles Babbage (1792-1871) was a English mathematician credited with being the inventor of the computer.
He designed an "analytical engine", a general-purpose mechanical computing device for performing different calculations according to a program input on punched cards (an idea borrowed from the Jacquard loom).
This device was never built, but it embodied many of the principles on which modern digital computers are based.
As a young man Babbage assisted John Herschel with his astronomical calculations.
He became involved with calculating machines when he worked on his mechanical "difference" engine for the British Admiralty, though this was never completed.
