Charles Hollenberg was an orthopaedic surgeon at his family’s clinic, the Hollenberg Clinic, in Manitoba, Winnipeg, Canada. He was born in Manitoba on 10 October 1909, into a Jewish family, the son of Moses Hollenberg, a storekeeper of dry goods, and Sarah Etta Hollenberg née Rosenstock. In 1903 his parents and two older sons Michael and Abraham had emigrated to Canada from Galicia in Eastern Europe. Hollenberg attended Norquay School and St John’s High School, both in Winnipeg, and then studied at Manitoba Medical College. He qualified with an MD in 1932 and became a member of the College of Physicians and Surgeons of Manitoba in 1933. In 1937 he married Alice (or Alyce) Joyce Yaffee from Elgin, Illinois, USA. In 1939 he was listed in the England and Wales Register as living in Grimsby, where he worked at Grimsby District Hospital. During the Second World War he served with the Royal Canadian Army Medical Corps. In 1943 he was promoted to major and in 1945 was awarded an MBE. *The Daily Chronicle*, a local paper in DeKalb, Illinois, reported that Hollenberg and his wife were received by King George VI at Buckingham Palace on 22 June 1945, the MBE given for his work as deputy assistant director of medical servicers on D-Day: ‘Major Hollenberg was given this outstanding recognition for his service in organising emergency hospitals under fire just behind the British front line in continental Europe.’ After the war Hollenberg stayed on in Europe, gaining a masters degree in orthopaedic surgery at the University of Liverpool in 1946 and his fellowship of the Royal College of Surgeons of England in 1947. In 1948 he returned to Winnipeg, where he joined the Hollenberg Clinic, recently established with his brothers Michael, Abraham, Joseph and Jacob, and sisters-in-law, Dorothy, who was married to Joseph, and Esther, who was married to Jacob. All were doctors. The two women were amongst the first small group of female Jewish physicians in Canada. The clinic closed in 1958. Hollenberg died on 2 November 1995 at the age of 86.
