Biography Irwin was born in Northern Ireland and moved to Southern Rhodesia (now Zimbabwe) in 1949 where he met Reay Smithers, then director of the National Museum of Southern Rhodesia in Bulawayo, and soon became collector with the museum. In 1959 he was assistant curator of vertebrates, subsequently curator of ornithology, in 1975 regional director in Bulawayo, and finally associate ornithologist, and as of 2012 a natural history librarian in Norfolk.The Museums Renowned Past Curators
Irwin worked closely with Constantine Walter Benson, an authority on central African birds. Together, they expanded the bird collection of the Natural History Museum of Zimbabwe until it became the largest both in Africa and in the southern hemisphere. It currently houses over 90,000 specimens from Zimbabwe and neighbouring countries and is one of the museum's greatest resources.
In 1981, Irwin published his best known work The Birds of Zimbabwe, but he had previously published the Bibliography of the Birds of Rhodesia in 1978, and co-authored A Checklist of Birds of Southern Rhodesia (with Reay Smithers) in 1957 and The Birds of Zambia (with Constantine Walter Benson) in 1971. He contributed also to The Birds of Africa series (with Emil K. Urban, Stuart Keith and C. Hilary Fry) and has published more than 300 scientific papers, many of them in the museum's journal Arnoldia.
