Born at Upton-on-Severn, the son of Charles Braddon, MRCS, who had been educated at the United Hospitals and at Grainger's School in the Borough. W L Braddon entered Guy's Hospital, where he gained in 1884 the Mackenzie-Bacon prize for his essay on nervous and mental diseases and in 1885 he was Burdett prizeman. His address in 1886, 1887, and 1888 is given as Upton-on-Severn, but he practised subsequently in the far east where he became interested in the causation of beri-beri. He rightly attributed it to the consumption of polished rice. His views were not generally accepted, but in 1913 he was rewarded with a research prize for his work on the disease. During the first world war he received a commission, dated 23 May 1917, as temporary major, RAMC. He died on 29 September 1936 at Serembam, Federated Malay States, having married Marion Philpott in 1897.
