Science Challenge #28

Challenge Question #1 -
Who invented the machine of which this picture is a part?
Mystery engine

This 1820 predecessor of modern electronic calculators was designed to calculate and to print nautical tables for ocean navigation purposes. It was invented by a professor of mathematics at Cambridge University in England. He built an experimental model in 1822. In 1832 his chief engineer assembled a section of the engine that still works flawlessly but the complete device was not built during the designer's lifetime. In 1834 he devised a more sophisticated device whose capabilities are strikingly similar to modern electronic calculators.
