Walter Stanley Hartroft earned B.Sc. in Medicine, University of Alberta, 1941 and an M.D. (1941) and Ph.D. (1950) at the University of Toronto. "W. Stanley Hartroft, M.D., Ph.D, F.R.C.P. spent his early years in the Banting and Best Department of Medical Research at the University of Toronto (1946- 1954), moved to Washington University in St. Louis as Mallinckrodt Professor and Chairman of the Department of Pathology (1954-1961), went back to Toronto to head The Research Institute of the Hospital for Sick Children (1961- 1970), and moved finally to the John A. Burns School of Medicine at the University of Hawaii...
During his time at Banting and Best Department, he took [on] a young graduate student from Detroit, Phyllis Merritt, who worked on the effect of salt and DOCA on the renal juxtaglomerular cells; he and Phyllis were married in1950.
In 1954 Stanley went to Washington University, and with enormous enthusiasm devoted himself to the development of the Department of Pathology, especially the experimental approach to the study of disease. Statistics, animal care, diet preparation, histochemistry, photomicroscopy, and electron microscopy flourished. Stanley and Phyllis worked until late into the night. Residents began participating in the experimental program. Funding of research was obtained, new equipment was purchased, and much of the department space was renovated. He continued his collaboration with Phyllis on J G cells, but also worked with W. A. Thomas, K. T. Lee, and me, and with J. S. Meyer, R. C. Ahlvin, B. B. Banson, J. W. Grisham, P. E. Lacy, E. A. Porta, M. Suzuki, W. J. S. Still, L. Recant, A. Mikata, and A. A. Dimakulangan. Hartroft’s faith in the experimental approach was exceeded only by his fear of bias, which he tried constantly to avoid. In 1961, in an argument with the administration over the need to develop a residency program in clinical pathology, utilizing the clinical laboratories of Barnes Hospi- tal, he resigned and left to head the Research Institute of the Hospital for Sick Children in Toronto.
