James Stott & Co.
Gas lighting manufacturers

Gas, heating and ventilation engineers James Stott & Co. (later Stotts of Oldham) was founded in 1878 by the younger of two well-known Lancashire cotton-mill architects, brothers Abraham H. and Joseph Stott. 1
It was their brother, James Stott (c. 1846–1934), however, who appears to have been the innovator in the field of gas, heating and ventilation engineering. He had a diverse career, starting as a bookbinder at 15, before working as an architect, while simultaneously running a temperance hotel, and suffered bankruptcy in 1870–1, perhaps due to his sideline in developing innovative gas valves. He was then successively a dentist, a 'gas engineer and farmer', and finally, ran a hotel and country estate in Cornwall, which showcased his own 'Plenum' ventilation system. 2
Stott's brothers also patented engineering designs, but it was James who developed the bestselling 'Mercurial' or Stott 'patent self-acting gas governor' in the 1870s. By 1885, it had 'won more awards in five years than all other makes in fifteen years'. The firm exported worldwide from their Vernon Works in Oldham, which also produced coin-operated gas meters, and later specialised in gas-powered catering equipment such as steamers and boilers. 3
James Stott separated from his wife and moved to Wales, where had a second family with hotelier Caroline Bailey (neé Matcham), whom he married in 1920 after the death of his first wife. Caroline was the sister of famous theatre architect Frank Matcham, with whom Stott occasionally worked, for example on the London Hippodrome in 1900. 4
James’s son Vernon Heywood Stott became director of the successful family company in Oldham and left a sizeable estate of £39,400 in 1939. 5
