Related documents: [0]  [DOC] William Henry Gaunt (born in Bradford, Yorkshire, 13 January 1874 – 31 October 1951) was an English transport engineer who began his working life developing and building gas-powered trams. He was educated at Manchester Grammar School before joining the Ashbury Company in Manchester as an apprentice. The works at Ashbury supplied the trams for Britain's first gas-powered tramway, the Blackpool, St Annes and Lytham tramway, operated by the British Gas Traction Company. Gaunt transferred to the tramway company in 1896, and then became manager of a similar gas-powered scheme at Trafford Park in 1896. Following the financial collapse of the Gas Traction Company in 1898 Gaunt was appointed manager of Trafford Park's gas and electric tramways, a position he held until 1905, when the operation of the electric line was taken over by the corporations of Manchester and Salford.
