1953 Obituary 
We have learned with deep regret of the death of Emeritus Professor Dempster Smith, which occurred at 6, Maule Terrace, Gullane, East Lothian, on Saturday last, March 21st.
Until his retirement during the war years, he bad been for a long period Professor of Mechanical Engineering at the Manchester College of Technology. He will be particularly well remembered by his active participation in the affairs of the profession of mechanical engineering in the North-West.
Dempster Smith was born on February 6, 1874, and was educated at the English School, Perth, and at the Glasgow and West of Scotland College.
He served a five-year apprenticeship with Sharp Stewart and Co., Glasgow, and on its completion continued with that firm for three years, during the latter part of which he was chief draughtsman in the machine tool department.
Dempster Smith then spent three years on the design staff of Sir W. G. Armstrong Whitworth and Co., Ltd., after which he went to Manchester to take up a post as chief designer with Hulse and Co., Ltd.
That appointment he relinquished In 1902 on becoming a lecturer in mechanical engineering and a demonstrator in the laboratories at the Manchester College of Technology. It was this appomtment that marked the beginning of Dempster Smith's long period of distinguished service - extending over forty years - to the College of Technology. There was only one break in Professor Smith's long career as a teacher of engineering. It occurred during the first world war, when for two years he served as works manager with Mirrlees, Bickerton and Day, Ltd., at Stockport.
Upon his retirement from the Manchester College of Technology, Dempster Smith received the title of Emeritus Professor. Professor Smith was elected an associate member of the Institution of Mechanical Engineers in 1907, and a full member in 1913. He did much to assist the work of the Institution and contributed several papers to its Proceedings. He served on the cutting tools research committee set up by the Institution in 1920, was for many years a member of council, and was also for some time the honorary secretary of the North-Western Branch. In recognition of these and many other services which he rendered to the Institution, the council elected him to honorary membership in 1941.
Professor Smith also took an active share in the work of the Manchester Association of Engineers, of which he was a past-president. His contributions to technical literature included books on Lathe Design and Engineers' Costs and Economical Workshop Production, and, in collaboration with Professor J. T. Nicholson, a lengthy series of articles on "The Rational Design of Machine Tools," which appeared in THE ENGINEER in 1912.
