Herbert Stanley MacDonald was born in 1901. In 1928 MacDonald formed a partnership with George Frederick Addison, trading as G.H.M. Addison and Son and H.S. MacDonald. Addison had joined his father George Henry Male Addison in business in 1919 and Addison senior had died in 1922. MacDonald and Addison are best known for the Queensland Brewery Company Building at 501 Ann Street, Fortitude Valley. The building is in the Functionalist Style and was constructed between 1940 and 1942. It was added to the Queensland Heritage Register on 21 October 1992 (as the Credit Union Australia Building). In 1940 MacDonald and Addison dissolved their partnership and MacDonald began trading under his name. In 1952 he designed the Substation No. 75 at 93 Wellington Rd, East Brisbane for the City Electric Light Company (now Energex). This building is listed as a Brisbane Local Heritage place. MacDonald died in 1972.
