ABSTRACT
After receiving her BSc from the University of Melbourne, Australia, Marie set sail for England to pursue a career. In London, she worked with Dr P.L. Mollison for 10 years, and together they published many articles in the areas of hemolytic disease of the newborn, red cell survival, red cell preservation, and the identification of new antibodies. In 1957, she married Dr John Crookston and moved to Toronto. In Toronto, she directed and participated in various research projects while acting as a consultant to the Blood Transfusion Laboratory at Toronto General Hospital. Her enthusiasm for the field of Transfusion Medicine, her keen eye, and intellect resulted in many discoveries, both on her own or in collaboration with others. Marie is now retired but is fondly remembered by Blood Transfusionists in Canada and elsewhere.
