Recipient of the Canada Gairdner International Award, 1963
"In recognition of his outstanding contributions to the knowledge of micro anatomy and human cytogenetics and, in particular, for his discovery of a technique for the specific identification of male and female cells, thus opening vast new areas for research into the normal and abnormal development of bodily structures, which have led to an improved understanding of several important congenital anomalies including some errors of sexual development and some forms of mental retardation."
