Jonathan Hornblower biography
Jonathan Carter was born July 5, 1753 in Chacewater, England. He worked for James Watt. Seeking to improve on Watt's steam-engine design, Carter devised the first reciprocating compound steam engine, which made a significant contribution to efficiency. In 1792 he was forced to withdraw his application for an extension of the patent after Watt protested that the design too closely mirrored his own.
