1949 Obituary 
"HENRY THOMAS CREWE, whose death occurred on 14th October 1947, at the great age of ninety, was a Member of the Institution for nearly half a century, having been elected in 1898. He was educated privately and served his apprenticeship from 1872 to 1879 in the works and offices of Mr. Hammond, master carpenter, of Crouch End, London. He then filled positions successively as manager to an engineering works at Blackheath; gas-engine and electric light department of Messrs. Dick Kerr and Company, Ltd., Kilmarnock; and the Dawson Gas Engines Syndicate until 1898 when he went into business on his own account as a mechanical and electrical engineer; he directed his own business until his retirement in 1926.
Mr. Crewe formed a collection of some of the earliest types of electric light bulbs, which was shown at the Wembley Exhibition and is now permanently housed in Bath. His inventions, for which he took out numerous patents, covered a wide range and included devices for dispensing with putty for roof glazing and washers for taps."
