Ernest A. McCulloch
Ernest Armstrong McCulloch (27 April 1926 – 20 January 2011) was a University of Toronto cellular biologist, best known for demonstrating – with James Till – the existence of stem cells. Biography McCulloch was born in Toronto, Ontario, Canada on 27 April 1926, and was educated at Upper Canada College and the University of Toronto. Ernest McCulloch received his MD in 1948 from the University of Toronto. Upon graduation, he began his education in research at the Lister Institute in London, England. In 1957 he joined the newly formed Ontario Cancer Institute, where the majority of his research focused on normal blood-formation and leukaemia. Together with his colleague, Dr. J.E. Till, McCulloch created the first quantitative, clonal method to identify stem cells and used this technique for pioneering studies on stem cells. His experience in hematology, when combined with Till's experience in biophysics, yielded a novel and productive combination of skills and interests. ...

Till & McCulloch
Till & McCulloch are James Till and Ernest McCulloch who, while studying the effect of radiation on the bone marrow of mice at the Ontario Cancer Institute, in Toronto, demonstrated the existence of multipotent stem cells in 1961.
