Claude Bertram Russell Mann was a general surgeon at the Royal Brisbane Hospital. Born in Cairns, Queensland on 30 March 1918, he was the son of Edgar Stanley Mann, an accountant, and his wife Grace Priscilla née Mayers. He was educated at Cairns State School, Eagle Junction (Brisbane) State School and the Brisbane Boy’s Grammar School which he attended with the R H Roe bursary. At the University of Queensland Medical School he won the W N Robertson medal for gaining first place in his year in the final examinations. He served as a captain in the Australian Army Medical Corps from 1942 to 1946. Travelling to the UK, he continued his medical studies in London at the British Postgraduate Medical School at Hammersmith Hospital where he was mentored by Richard Harrington Franklin and Ian Aird. This was followed by work as a surgical registrar at the Kingston-on-Thames Hospital. He passed the fellowship of the college in 1948 having won the Hallett prize the previous year. On his return to Australia he became a senior surgeon at the Royal Brisbane Hospital (working with Franz Konrad Saddler Hirschfeld) and at the Repatriation General Hospital. He married Ethel Corkey McKee in Northern Ireland four days before he returned to Australia. They had two daughters, Cheryl and Gail, and a son, Russell. He enjoyed playing tennis – he had been the Queensland junior champion in his youth – and had been a member of the Davis cup practice team. He died in 2014.
