Morgenthaler was a general practitioner in Canada. He not only performed abortions when doing so was still illegal, but admitted to it and campaigned publicly for legalisation. His courage and dedication over many years landed him an eighteen-month jail sentence. In the end, he achieved more than just legalisation: the abortion law was struck from the Canadian statute books in 1988 without substitution and abortion is no longer subject to criminal law in Canada.
