Clarke, Irwin & Company was a Canadian publishing house based in Toronto, Ontario. Established in 1930, it was purchased by Thomas Nelson Publishing in 2002. The company published works by prominent Canadian authors, artists, and poets, including Robertson Davies, Emily Carr, A.Y. Jackson, Adele Wiseman, Timothy Findley, and Alden Nowlan. The company was also known as a producer of educational works and textbooks.
In 1930, William H. Clarke, formerly of Maclean-Hunter Publishing and the Macmillan Company of Canada, partnered with John C.W. Irwin, a Toronto bookseller, to start a new publishing house. They were joined by Irene Irwin Clarke, Clarke's wife and Irwin's sister. The company quickly established publishing arrangements with several British and American book companies, including the University of London Press, George G. Harrap & Co., Henry Holt & Co., and Rinehart & Co. The company started a lucrative trade in public school and university textbooks in the mid-1930s.
William Clarke began a partnership with the Oxford University Press (OUP) in 1936. The Canadian division of the company had seen hard times during the Great Depression, and, after the death of its director Samuel Gundy, William Clarke was able to take control of OUP. The two imprints operated from the same address for the next thirteen years. The partnership was responsible for the first Bible completely printed and bound in Canada.
