Member of the Union nationale, Johnson died in office while he was the premier of Québec. Two of his sons became premier after him, but for different parties: first
Pierre-Marc for the Parti Québécois from October 3 to December 2, 1985, then
Daniel for the Québec Liberal Party from January 11 to September 11, 1994. Wouldn't it be interesting to be a fly on the wall during that family's Christmas dinner?
