Gemm., 1988, 21, 3 Douglas Wheeler It is with deep regret that we report the death on Saturday 7 May 1988 of Douglas Wheeler, former Assistant Secretary of the Gemmological Associa­ tion of Great Britain and Deputy Secretary of the National Association of Goldsmiths. Douglas was born on 15 May 1922 in East Ham, London, and joined the staff of the G A and NAG in 1936 at the age of 14. He served both associations continuously except for a period of five years in HM Forces. On his 19th birthday he volunteered for the RAF and after flying training in Canada saw active service in Europe. He was commissioned at 21. Douglas returned to civilian life in 1946 and rejoined the Associations, working alongside the late Gordon Andrews and his brother, the late Harry Wheeler, both of whom had also returned from the services. He studied at Chelsea Polytechnic as an evening class student and became an FGA in 1948. He was appointed Assistant Secretary for the G A in 1973 and Deputy Secretary of the NAG in 1976. Douglas retired from business in November 1983. He said at that time that he had greatly enjoyed his years with the two Associations and had been lucky in the people he had met and worked with. He looked forward to a new life of retirement in Norfolk. He leaves his wife, Kathleen, two sons, Michael and Stephen and grandchildren. © Copyright the Gemmological Association ISSN: 0022-1252 J.J.

    III Preparatory to anything else Mr Bloom brushed off the greater bulk of the shavings and handed Stephen the hat and ashplant and bucked him up generally in orthodox Samaritan fashion, which he very badly needed. His (Stephen’s) mind was not exactly what you would call wandering but a bit unsteady and on his expressed desire for some beverage to drink Mr Bloom, in view of the hour it was and there being no pumps of Vartry water available for their ablutions, let alone drinking purposes, hit upon an expedient by suggesting, off the reel, the propriety of the cabman’s shelter, as it was called, hardly a stonesthrow away near Butt Bridge where they might hit upon some drinkables in the shape of a milk and soda or a mineral. But how to get there was the rub. For the nonce he was rather nonplussed but inasmuch as the duty plainly devolved upon him to take some measures on the subject he pondered suitable ways and means during which Stephen repeatedly yawned. So far as he could see he was rather pale in the face so that it occurred to him as highly advisable to get a conveyance of some description which would answer in their then condition, both of them being e. d. ed, particularly Stephen, always assuming that there was such a thing to be found. Accordingly, after a few such preliminaries, as, in spite of his having forgotten to take up his rather soapsuddy handkerchief after it had done yeoman service in the shaving line, brushing they both walked together along Beaver Street, or, more properly, lane, as far as the farrier’s and the distinctly fetid atmosphere of the livery stables at the corner of Montgomery street where they made tracks to the left from thence debouching into Amiens Street round by the corner of Dan Bergin’s.
