DONALD GRANT MACKINTOSH, M.B.E., whose death occurred at Sutton Coldfield on 24th September 1942, in his sixty-fourth year, was elected an Associate Member of the Institution in 1907 and was transferred to Membership in 1928. For some years he had rendered valuable services to the Institution as a member of the Committee of the Midland Branch; he was Chairman during 1929-30, in which capacity he served as a Member of Council.
He was educated at King Edward VI School, Birmingham, and served his apprenticeship with Messrs. Messenger and Sons, completing his technical training at the Technical School, Birmingham, in 1903. After five years' experience in the drawing office of Messrs. Braithwaite and Kirk, bridge builders, West Bromwich, he was made chief draughtsman and subsequently became assistant works manager. His association with that firm, now known as Messrs. Braithwaite and Company, continued, with the exception of brief intervals of employment with other local engineering works, until 1934 and during that long period, after occupying the post of chief draughtsman until 1916, he was then appointed manager, in which position Mr. Mackintosh was responsible for the design and manufacture of all classes of bridge and constructional steelwork in addition to the supervision of the company's works at Newport, Monmouthshire, since 1927.
From January 1935 to August 1941 he was manager of the firm of Walker Brothers, Ltd., Walsall, and until his death he acted in the same capacity for Messrs. E. C. and J. Keay, Ltd., of Darlaston. He took a keen interest in the training of young engineers, and was deputy-chairman of the Higher Education Committee of West Bromwich until within a year of his death.
