(Suggest an Edit or Addition)

According to Wikipedia, David Shugar was a professor of the University of Warsaw. After the First World War, he settled as a child with his parents in Canada. In 1936 he concluded his education of physics at McGill University in Montreal and obtained his doctorate in 1940. Since January 1941, he did research in biophysics in the laboratory of Research Enterprises, Limited, a Crown Company in Leaside near Toronto, later served in the Canadian Marines with the rank of Electrical Sub-Lieutenant R.C.N.V.R. In 1946 he entered the employ of the Department of National Health and Welfare.
