Albert George Clark was born in St Giles, London, in June 1880. He married Alice Harriet Cooper in August 1902 and the couple had three children. Clark worked on the London Underground as a bricklayer and tunnel labourer. During the First World War, it is thought that he served in a tunnelling company, possibly the Royal Engineers. He travelled to India in the 1920s to work on railway construction. It is known that he worked on the construction of tunnels on the Malay Peninsula. He returned to England in April 1931; the passenger list of the 'RMS Ranpura' listed Clark's occupation as tunnel foreman. He died in Ware, Hertfordshire, in August 1944, where he had been the lock-keeper for some years.
