Scottish engineer.

Son of the artist Alexander Nasmyth (1758–1840), he is known mainly for his invention of the steam hammer (1839), an important metallurgical tool of the Industrial Revolution. He also devised tools such as a planing machine, a steam pile driver, and a hydraulic punching machine, and he manufactured more than 100 steam locomotives.

▪ Scottish engineer
born Aug. 19, 1808, Edinburgh, Scot.
died May 7, 1890, London, Eng.

      British engineer known primarily for his invention of the steam hammer.

      Nasmyth showed an extraordinary mechanical inclination while still a schoolboy in Edinburgh, building successful model steam engines. For two years he worked in Henry Maudslay's machine shop in London and subsequently moved to Manchester, where rapid industrialization was in progress. In 1836 he began to build his own foundry near the junction of the Bridgewater Canal with the newly opened Liverpool and Manchester Railway. He made machine tools of all kinds along with a variety of steam-powered machines. Isambard Kingdom Brunel (Brunel, Isambard Kingdom), when designing his steamship Great Britain, originally made plans for paddle wheels of exceptional size. Nasmyth solved the challenging problem of forging the drive shaft by designing and fabricating a powerful steam hammer, which he patented in 1842. Although the Great Britain was eventually furnished with screw propellers instead of paddle wheels, the steam hammer immediately became an important part of the metallurgical arsenal of the Industrial Revolution.

      Besides steam hammers, Nasmyth manufactured more than 100 steam locomotives, many small high-pressure steam engines, and a variety of pumps, hydraulic presses, and other machines. At the age of 48 he retired from the foundry in order to devote himself to his hobby, astronomy. He wrote The Moon: Considered as a Planet, a World, and a Satellite (1874).
