John Symonds Lyon Browne (April 13, 1904[1] – January 21, 1984) was an English-born Canadian physician.
Browne returned to McGill as a research fellow, later becoming a professor of medicine, Medical Department chairman and director of the Royal Victoria Hospital.
He was forced to leave those positions due to failing eyesight but served as chairman of the Department of Investigative Medicine from 1955 until his retirement in 1960.
During his time at McGill, he pressed for the addition of more biochemistry and physiology in the undergraduate curriculum for clinical medicine.
[3] Browne was named to the Canadian Medical Hall of Fame in 1994 for his efforts to create co-operation between the English and French-speaking physicians of Quebec.
