Theatrum Machinarum Generale, (The General Theory of Machines) was written by the German physicist, scientist, mathematician, and engineer Jacob Leupold (1674–1727). The work is the first systematic analysis of mechanical engineering. Theatrum Machinarum consists of nine volumes, containing more than two thousand pages of text, and five hundred copper plate engravings. It included, ahead of its time, a design for a high-pressure non-condensing steam engine, the likes of which were not built until the early 19th century. The Scottish steam engine inventor and mechanical engineer James Watt, (30 January 1736– 25 August 1819), taught himself German to read the work, Watt’s work would herald the Industrial Revolution.
