"THE LATE MR. D. M. SHANNON.

Mr. David McCrorie Shannon, whose death we regret to have to record, took place suddenly at the early age of fifty-one on December 7, was connected throughout his life with the design and construction of marine Diesel engines, and had latterly occupied a position on the staff of Messrs. “ R.N.” Diesel Engine Company, Britannia House, ...ampton-street, London, W.C.l. He was born in Glasgow and was educated at the Royal Technical College and at Glasgow University. He served his apprenticeship with Messrs. A. and P. W. McOnie, engineers, Glasgow, and afterwards worked for two years in the gas-engine and producer-gas plant departments of Messrs'. William Beardmore and Company, Limited, Parkhead Works, Glasgow. His next appointment was with Messrs. Duncan Stewart and Company, Limited, Glasgow, where he was engaged for about twelve months on the design of vertical high-speed gas engines. Proceeding to Barrow-in-Furness in 1907 he took up a position on the designing staff of the submarine department of Messrs. Vickers Limited, which he continued to occupy for some three years; during this time he carried out useful work on the design of airless-injection gear. In 1910, Mr. Shannon was given control of the oil-engine department of Messrs. William Beardmore and Company, Limited, Dalmuir, and in the following year was responsible for the design and testing of one of the first British direct-reversing heavy-oil engines, afterwards installed on board a yacht for the Marquis of Graham.

In 1912 Mr. Shannon became technical adviser to Messrs. Fairfield Shipbuilding and Engineering Company, Limited, Glasgow, and after remaining there for two years, joined Messrs. Cammell Laird and Company, Limited, Birkenhead, in December, 1914. As head of the Diesel-engine department, he was largely responsible for the design of the Cammellaird-Fullagar opposed-piston, two-stroke, heavy-oil marine engine. He severed his connection' with Messrs. Cammell Laird in 1926 upon his appointment to the position of British manager of the oil-engine department of Messrs. Fiat (England), Limited, in which he did much development work. Some years later Mr. Shannon resigned his position with Messrs. Fiat and became associated for a short time with Messrs. Newbury Diesel Company, but relinquished this post in September, 1932, to take up an appointment on the sales staff of Messrs. “ R.N.” Diesel Engine Company, which he was holding at the time of his death. Mr. Shannon was elected a member of the Institution of Mechanical Engineers in 1919, and of the Institution of Naval Architects in 1928."

* 1933 Obituary

IT is with deep regret that we have to record the death, at the comparatively early age of fifty-one, of Mr. David McCrorie Shannon, a well-known personality in the marine oil engine industry. Mr. Shannon received his early training with Vickers Ltd. at Barrow-in-Furness and for some years was attached to the firm's oil engine department. Shortly after the outbreak of war he joined Cammell Laird and Co., Ltd., of Birkenhead, and as head of the oil engine department was responsible for the design and construction of the Camellaird-Fullagar opposed-piston two-stroke oil engine, which was subsequently fitted to many ships and applied for land work. In 1926 Mr. Shannon joined the Fiat Company and was responsible for the introduction of the Fiat oil engine into Great Britain and the establishment of Fiat British Auxiliaries, Ltd. Quite recently Mr. Shannon designed a successful oil fuel lubricating oil filter called the "Rotoklene" strainer, which we have described. After a short time with the Newbury Diesel Company, Ltd., of Newbury , Mr. Shannon took up an appointment as sales engineer with the "R.N." Diesel Engine Company, Ltd., of Altrincham and London, in whose service he was at the time of his death. He had many friends in the marine oil engine industry, and his untimely death shortly before he was to have been married will be widely regretted, both in this country and abroad.
