Theodore G.H. Drake was born in Webbwood, Ontario in 1891 and received a medical degree from the University of Toronto in 1914. After training at the Hospital for Sick Children and spending two years at Harvard University, Drake joined the HSC staff in 1929, setting the path that earned him an international reputation.
Alongside Frederick FItzgerald Tisdall, Theodore G.H. Drake was responsible for the development and production of Pablum, a cereal-like food meant for the improvement of infant nutrition. Pablum was a combination of minerals and vitamins needed by growing children and a ground, pre-cooked mixture of starches. The product dominated infant feeding for decades after its introduction in 1930 and its royalties contributed to supporting the research at the hospital for the next twenty-five years.
