Dick studied scarlet fever whilst serving the Army [Medical Department |Army Medical Corps] during World War I. Dick continued with his research into scarlet fever following the war, and in 1923, in collaboration with his wife Gladys [Rowena Dick], managed to locate the cause of the disease in a toxin produced by a strain of Streptococcus bacteria. Using this, they were able to create an antitoxin for treatment and a non-toxic vaccine for immunization. In 1933, Dick and his wife were awarded the Cameron Prize for Therapeutics of [the University of Edinburgh].
He was a professor of clinical medicine at Rush Medical College, Chicago, and then became the head of the department of medicine at the University of Chicago.
