Cass Science Hall was the original Science Hall for the St. Dunstan’s College campus. Built in 1939, it was instrumental to St. Dunstan’s activating its university charter. In 1967, the building was assigned exclusively to chemistry and named Cass Chemistry Building in memory of Father Frederick Cass, the first priest to teach chemistry at SDU (1931-1964). His devotion to St. Dunstan’s, and to generations of students, created a lasting legacy. In 1997, the building was rededicated to Father Cass and the floors of the building named in honour of the priests who pioneered in the study of science at St. Dunstan’s University: Rev. A. Charles MacDonald Engineering Rev. George A. MacDonald Physics Rev. Edmund Roche Mathematics Rev. Richard Ellsworth Biology Cass Science Hall is now home to the Departments of Engineering, Mathematics & Statistics and Computer Science & Information Technology.
