(Stark, 2000, p. 3) Written just over a decade ago, this call for increased awareness of the history of Canadian psychology and the role women have played in it is now being heeded.

In doing so, we provide a counterweight to the extensive historiography on women in American psychology that began in the 1970s and has since expanded to encompass many important historical studies (e.g.
