HELEN SAWYER HOGG PUBLIC LECTURE
The Helen Sawyer Hogg Prize Lecture was initiated in 1985 by the Canadian Astronomical Society with the participation of the Royal Astronomical Society of Canada, the Planetarium Association of Canada, and the Royal Canadian Institute. It continues as an annual public lecture co-sponsored by Cascatrust and the RASC, given alternately at the annual meetings of both societies, in recognition of the sustained and diverse contributions of Helen Sawyer Hogg to public appreciation of the universe around us. Selection of the Lecturer is made by a committee consisting of the Presidents of CASCA and the RASC, and the chairman of the Local Organizing Committee hosting the meeting (either CASCA or RASC).
