George Mack (1899-1963) was mainly a museum ornithologist and collector. He migrated from Britain to Western Australia in 1919. He worked at the National Museum of Victoria from 1923 to 1945. During this time, he published a revision of the Australian species of the fairy-wren genus Malurus. He then worked at the Queensland Museum from 1945, rising to become director in 1963, the year of his death. It was his controversial action in shooting a scarlet robin during the Royal Australasian Ornithologists Union (RAOU) campout in Marlo, Victoria in 1935 that catalysed change in the RAOU's attitude to collecting.
