William Murdoch (sometimes spelled Murdock) (21 August 1754 – 15 November 1839) was a Scottish engineer and inventor.
Murdoch was employed by the firm of Boulton and Watt and worked for them in Cornwall, as a steam engine erector for ten years, spending most of the rest of his life in Birmingham, England.
Murdoch was the inventor of the oscillating cylinder steam engine, and gas lighting is attributed to him in the early 1790s, also the term "gasometer". However, Archibald Cochrane, ninth Earl of Dundonald, had already in 1789 used gas for lighting his family estate. Murdoch also made innovations to the steam engine, including the sun and planet gear and D slide valve. He invented the steam gun and the pneumatic tube message system, and worked on one of the first British paddle steamers to cross the English Channel. Murdoch built a prototype steam locomotive in 1784 and made a number of discoveries in chemistry.
Murdoch remained an employee and later a partner of Boulton & Watt until the 1830s, and his reputation as an inventor has been obscured by the reputations of Boulton and Watt and the firm they founded.
William Murdoch was born in Lugar near Cumnock, East Ayrshire, Scotland, the third of seven children and the first son to survive beyond infancy. A son of John Murdoch, a former Hanoverian artillery gunner and a Millwright and tenant of Bello Mill on the estate of James Boswell in Auchinleck, he was educated until the age of ten at the Old Cumnock Kirk School before attending Auchinleck school under William Halbert, author of a highly regarded arithmetic textbook. Murdoch excelled in mathematics. Murdoch also learned the principles of mechanics, practical experimentation and working in metal and wood by assisting in his father's work. Together with his father, he built a "wooden horse" about 1763. His "Wooden Horse on Wheels" was a tricycle propelled by hand cranks. There are reports that in his youth Murdoch was responsible for the construction of one of the bridges over the River Nith; this possibly derives from his father's work in building the Craikston Bridge over Lugar Water in 1774, which William would have been involved in. He is also said to have carried out experiments in coal gas, using coal heated in a copper kettle in a small cave near his father's mill. However, there is no contemporary documentation.
