Conrad Bremer was a consultant physician at the Royal Infirmary in Sunderland. He was born in Hull, the son of Frederick Henry Christian Bremer, a fruit importer and exporter. He was educated at Sedbergh School and then went on to Leeds University to study medicine.
From 1940 he held junior hospital appointments at Harrogate and District General Hospital. In January 1943 he joined the Royal Air Force as a medical specialist, eventually attaining the rank of squadron leader.
On returning to civilian life, in 1946, he became a senior registrar at the General Infirmary in Leeds. He was appointed as a consultant physician to the Royal Infirmary, Sunderland, in April 1950.
He had many interests outside medicine. From childhood to the onset of the war he bred champion Scottish terriers. From 1950 to 1967 he kept his own horses and rode regularly, occasionally hunting and taking part in show jumping competitions. He also played badminton and maintained interests in photography and music.
He married Margaret Sharman in 1939 and they had two daughters.
