He was born in 1878 and received his technical education at the City and Guilds Technical College, Finsbury, and at the Polytechnic, Regent Street, London. After four years' experience as assistant to the London Distilling and Yeast Co, he entered the service of the Gas Light and Coke Co in 1900, as a chemist, at Beckton. Subsequently, he held the positions of junior assistant and senior assistant engineer, before his transference in 1917 to Kensal Green as chief assistant engineer. In 1927 he was appointed station engineer at the Richmond Gas Works, where he was responsible for the erection and putting into operation of a carbonizing plant comprising forty retorts. His final appointment which he held for sixteen years was that of station engineer at Southend.
