Arthur James Rochfort Allman (1873-1948)
1949 Obituary 
"ARTHUR JAMES ROCHFORT ALLMAN, who was born in 1873, retained a connection with the London area during the whole of his professional career. He was educated at the Latymer Foundation Schools, Hammersmith, and at the Regent Street Polytechnic, London. After serving a five years' apprenticeship, beginning in 1892, with Messrs. J. H. Gwynne, Ltd. (now Gwynnes Pumps, Ltd.), of Hammersmith, he filled temporary positions with Messrs. John I. Thornycroft and Company, Ltd., and the Daimler Motor Company. In 1901 he was appointed works manager to Messrs. Smith and Dowse, Ltd., of Isleworth, for whom his chief duties were the production and testing of internal combustion engines.
He remained with that firm for thirteen years, after which he became manager to Mr. T. H. Taylor, of Hammersmith, a former fellow apprentice. This association was maintained until his retirement in 1935. During that long period the firm was responsible for numerous inventions, the models for which were largely made by Mr. Allman, amongst which, one of a tar distilling plant may be seen at the Science Museum, South Kensington. They also specialized in electrically driven potter's wheels which were used in all parts of the world. Mr. Allman's death occurred at West Horsley, Surrey, on 27th February 1948. He had been an Associate Member of the Institution since 1912."
