Rupert Hallam and the development of dermatology in Sheffield.

(Arthur) Rupert Hallam worked as a dermatologist in Sheffield from 1911 to 1944. Early in his career, he also specialized in diagnostic radiology and established this speciality in Sheffield. Hallam performed investigative work on the aetiology of papular urticaria and erythema multiforme, the prognosis of psoriasis, and the aetiology of chilblains. He was an original member of the British Association of Dermatologists from 1920 becoming president in 1935. He also helped to found the North of England Dermatological Society. He was an innovator in both clinical and administrative matters and was the first British dermatologist to develop a full-time training post in the specialty.
