Hugh de Wardener

Hugh Edward de Wardener CBE MBE(Mil.) FRCP (8 October 1915 – 29 September 2013) was a British medical doctor who was an expert in the treatment of kidney disease. He was a pioneer of dialysis treatment and the first doctor in the United Kingdom to perform renal biopsies.
Educated at Malvern College and St Thomas' Medical School, he worked at a hospital until the outbreak of World War II. He joined the Royal Army Medical Corps during the war and was posted to Singapore soon before its fall to the Japanese. He spent the rest of the war as a POW in the notorious Changi camp, during which time while treating fellow prisoners he established that beriberi is caused by a deficiency of Vitamin B1, not as was previously thought by excessive consumption of alcohol. He was awarded a military MBE in 1946.
He was Professor of Medicine, University of London, Charing Cross Hospital, 1960–81, and subsequently Emeritus professor. He was Honorary Consultant Physician to the Army, 1975 1980. He was appointed CBE on his retirement in 1982.
