Leonard Rogers was born at Hartley House near Plymouth on 18 January 1868. He attended St Mary’s Hospital medical school from 1886 and passed the final examination for the FRCS (Fellow of the Royal College of Surgeons) in 1892.

In 1893 he entered the Indian Medical Service and conducted research as regimental medical officer, showing aptitude in this capacity. He was posted to the Bengal civil medical department at Calcutta in 1900, where he acted for the professor of pathology in the medical college and was the virtual holder of the post after 1904, and confirmed in it in 1906. Apart from the various tropical diseases that he worked on, leprosy appealed to him on both social and scientific grounds. He investigated the efficacy of chaulmoogra oil and stimulated others to recognise the early stages of leprosy. His interest in leprosy was life-long, especially epidemiology, prophylaxis and treatment.

Rogers was instrumental in devising plans and raising funds for the construction of the Calcutta School of Tropical Medicine, established in 1914. He also founded BELRA (British Empire Leprosy Relief Association) in 1923.

He left India in 1920 due to ill health and retired from the Indian Medical Service in 1921, becoming a lecturer at the London School of Tropical Medicine. He was appointed to the India Office medical board as member in 1922 and was promoted to president in 1928.

In 1911, Sir Rogers was appointed CIE and knighted in 1914. He was awarded KCSI in 1932 (an honour usually reserved for Governors and members of the Viceroy’s Council), and in 1933-5 was president of the Royal Society of Tropical Medicine and Hygiene.

Rogers died in Truro after a fall, on 16 September 1962.
