Wilfred Bigelow

Wilfred Bigelow (born 1913 in Brandon, Manitoba) is a heart surgeon famous for his role in developing the artificial pacemaker. He gained his MD from the University of Toronto in 1938

In the 1950s, Bigelow developed the idea of using hypothermia as a medical procedure. This involves reducing a patient's body temperature prior to an operation in order to reduce the amount of oxygen needed, making heart operations safer.
