Encyclopedia > Robert Davidson

Robert Davidson of Aberdeen was a Scottish inventor who built the first known electric locomotive in 1837. Born and died (1804-1894) in Aberdeen, North East Scotland,where he was a prosperous chemist and dyer. Educated in the city, at Marischal College, he became interested in the new electrical technologies of the day. He staged an exhibition of electrical machinery at Edinburgh, Scotland, and later, at the Egyptian Hall, Piccadilly, London. His electric railway locomotives was tested on the Edinburgh-Glasgow line in 1842. The first known working electric locomotives was made in New England in 1837, but this was only a working model. Davidson's 'Galvani' was a four wheeled machine, powered by zinc-acid batteries. It was capable only of carrying itself at 6mph (approx 10km/h). It did not haul any passengers or cargo. In a later report Michael Faraday calculated that burning zinc in a battery was 40 times more expensive than burning coal in a firebox. Later experiments in America proved him correct. Financially viable electric traction developed from the 1860s when the dynamo was invented and perfected. Davidson lived to see these developments- his reaction to the opening of the City & South London Tube was to commission a new set of business cards, that read 'Robert Davidson.
