Spurred by postwar growth in the student population and the discovery of oil in Leduc in 1947, the University of Alberta underwent expansion through the 1950s that continued through the 1960s as the baby-boom generation swelled the enrolment ranks. These two decades also saw expansion of campus buildings, including new buildings for the faculties of physical education and education, and the Cameron Library. The University of Alberta Press, concentrating on western Canadian history, general science and ecology, was founded in 1969.
