Cardozo, William Warrick (1905–1962)

US physician and paediatrician who made pioneering investigations into sickle-cell anaemia. He concluded in 1937 that the disease was inherited following Mendelian law and almost always occurred in black people or people of African descent; not all persons with sickle cells were necessarily anaemic and not all patients died of the disease.

Cardozo studied at Ohio State University. In 1937 he started private practice in Washington, DC, and was appointed part-time instructor in paediatrics at Howard University College of Medicine and Freedmen's Hospital, later being promoted to associate professor.

Cardozo's investigations were published in the Archives of Internal Medicine as ‘Immunologic studies in sickle cell anaemia’.
