Sir William Peterson solidified McGill’s growing reputation as a prominent research university. During his tenure as Principal (1895-1919), a graduate school was established under his leadership and several programs were created.
In 1906, Peterson helped secure the integration of Macdonald College into the University . Peterson took a close interest in student affairs and the Students’ Society of McGill University was formed during his tenure, providing a degree of student self-government.
Peterson also oversaw the development of the McGill University College of British Columbia, which later became the University of British Columbia.
