SAMUEL DAVID CRAIG was connected during the whole of his career with the Belfast firm of Messrs. Robert Craig (Engineers), Ltd., which was founded by his father in 1882. Mr. Craig was born in Belfast in 1886 and received his technical education at Belfast Municipal College of Technology.
From 1901 to 1907 he served his apprenticeship in his father's works, and was then made outdoor foreman, to supervise the erection of machinery manufactured by the firm. He was appointed shop foreman in 1912, in which year the firm added the making of air compressors to their activities; Mr. Craig was also placed in charge of this section of the work.
During the War he was attached to Larne Naval Base and was made engineer in charge of repairs to trawlers and drifters. In 1916 when the firm was reconstituted as a limited liability company, he was appointed a director and manager of the machine shop. Besides air compressors, he was responsible for the production of steam engines, single-stage and multistage centrifugal pumps, and water turbines. More recently he was particularly concerned with the design and production of water turbines for hydro-electric power schemes. He was also responsible for the manufacture of the largest pumps ever manufactured in Belfast, namely, the storm-water pumping plants for Belfast Corporation, each of which have a capacity of 30,000 gallons of sewage per minute.
In 1930 Mr. Craig was elected an Associate Member of the Institution. His death occurred in Belfast on 15th April 1938.
