Sir William Watson Cheyne

Died 19 Apr 1932 at age 79 (born 14 Dec 1852).(1st Baronet) Scottish surgeon and bacteriologist who was a pioneer of antiseptic surgical methods in Britain. Educated at Aberdeen University, then as an assistant to Lord Lister, one of the foremost surgeons of his day, he helped to formulate antiseptic techniques which revolutionised 19th century surgery. In 1885, he defined the four operational principles to respect to avoid the infection: surgical washing of the hands of the surgeon, sterilization of the instruments, disinfection of the operational site and protection by fields, and reduction of the number of germs present in the environment. During the Boer War in South Africa, he was Consultant Surgeon to Lord Roberts and wrote extensively on the problems of surgery in warfare.
