Dr. Caroline Sophia Brown (1862-1936) was known for her keen intellect and seemingly inexhaustible physical vigour. She practiced medicine in Toronto for over twenty-five years, including at Women’s College Hospital. Her advocacy of women’s rights and her concern for the welfare of children are evident in her many achievements in education, medicine, and public service. A entry on Brown, written by Alison Li, appears this week in the latest volume of the Dictionary of Canadian Biography.
