Dr John W Macgregor Memorial Lecture

Dr. J.W. Macgregor
Department of Pathology
1951 - 1970

The Dr. J. W. Macgregor Memorial Lecture is a tribute to Dr. Macgregor who was appointed as Chairman of the Department of Pathology in 1951 and held that position for 19 years until his retirement in 1970. Born in Winnipeg in 1905, he obtained his medical degree from the University of Alberta. He established a residency training program in General Pathology after World War II and was also the Provincial Pathologist. While he is remembered as a stern and demanding task master he was also generous and kind and became affectionately known as "Black Mac". After his retirement he continued to work until 1975 as Emeritus Professor.
