Clinton Thomas Dent FRCS (7 December 1850 – 26 August 1912) was an English surgeon, author and mountaineer. Alongside Albert Mummery, Dent was one of the most prominent of the British climbers who attempted the few remaining unclimbed mountains in the Alps in the period known as the silver age of alpinism. Dent may have been the first person to have written – in his book Above the Snow Line (1885) – that an ascent of Mount Everest was possible. Dent was a well-known Senior Surgeon at the St George's Hospital medical school, London, Consulting Surgeon at the Belgrave Hospital for Children, Chief Surgeon to the Metropolitan Police from 1904, and a Fellow of the Royal College of Surgeons. The University of Cambridge awarded him the honorary degree of MCh. He wrote extensively, and his publications include studies of post-surgical insanity and heart surgery, and an account of the wounded in the Transvaal War, to which he had been posted as a correspondent for the British Medical Journal. He also had a special interest in dermatology. Dent died at the age of 61 after a 'mysterious attack of blood poisoning'.
