The Ontario Society of Artists (OSA) was founded in 1872. It is Canada's oldest continuously operating professional art society. When it was founded at the home of John Arthur Fraser, seven artists were present. Besides Fraser himself, Marmaduke Matthews, and Thomas Mower Martin were there, among others. Charlotte Schreiber was the first woman member in 1876 and showed work in the Society's Annual show of that year.
