Life and achievements
Castellani was born in Florence and educated there, qualifying in medicine in 1899. He worked for a time in Bonn and joined the School of Hygiene and Tropical Medicine in London in 1901. As bacteriologist with the Royal Society Commission on Sleeping Sickness in 1902, he went to Entebbe, Uganda with George Carmichael Low and Cuthbert Christy. He demonstrated the cause and means of transmission of sleeping sickness, discovered the spirochete of yaws, and did other original work in bacteriology and in parasitic diseases of the skin. In 1903 he was appointed Bacteriologist to the Government of Ceylon at the Central laboratory in Colombo and continued research in mycology and bacteriology, describing several new species of intestinal bacilli. He invented the absorption test for the serological identification of closely allied organisms. He left Ceylon in 1915 for Naples where he took the Chair of Medicine. He was involved during World War I in Serbia and Macedonia as a member of the Inter-Allied Sanitary Commission.In 1919 Castellani went to London as Consultant to the Ministry of Pensions. He became lecturer on mycology and mycotic diseases at the London School of Hygiene and Tropical Medicine, and established a consulting practice in Harley Street. He was also director of tropical medicine and dermatology at the Ross Institute prior to its merger with LSHTM. In late 1925 he arrived in New Orleans to direct a tropical medicine department at Tulane University School of Medicine, and would travel twice yearly between New Orleans and London to work on two continents. He was knighted in 1928 as an Honorary [Order of St Michael and St George|] and in 1934 his daughter Jacqueline Castellani married Sir Miles Lampson.
Castellani's enthusiasm for Royal and eminent patients such as Benito Mussolini clouded his reputation and during World War II he supported Italy against the Allies, becoming chief of the Italian Army's medical service. War correspondent Alaric Jacob discovered his looted quarters in Cirene in December 1941 and was tempted to pass his correspondence to his son in law Sir Miles Lampson, then British Ambassador in Egypt.
Castellani was President of the International Society of Dermatology from 1960 to 1964, which he had founded in 1959. He was also professor of tropical medicine at the State University of Louisiana and at the Royal University of Rome. He followed the Queen of Italy Marie José into exile in Portugal and ended his life as Professor at Lisbon's Institute of Tropical Medicine. Castellani died in 1971. Castellani's paint is still occasionally used to treat fungal skin infections.
The amoeba Acanthamoeba castellanii was discovered by him and later found to be an opportunistic human pathogen.
