1915 – He was born on the 9th day of April of this year in Danville, Quebec, Canada. His sons, Pierre-Marc Johnson and Daniel Johnson, Jr also became premiers of Quebec: Pierre-Marc as leader of the sovereigntist Parti Québécois for a brief period in 1985, and Daniel Jr as leader of the federalist Quebec Liberal Party for nine months in 1994.
1958 – He was the minister who started the Manic-5 hydroelectric project in this year.
1961 – This year, he was first elected leader of the conservative Union Nationale party.
1965 – His book entitled, Égalité ou indépendance (Equality or independence), made him the first leader of a Quebec political party to recognise the possibility of independence for Canada from the British Crown, and if the English-speaking Canadian did not want to be independent, then Quebec could do it alone.
1966 – He became the Premier of Quebec from this year until his death. His term was, among other things, qualified by tensions with the Government of Canada over constitutional matters, because as Premier of Quebec he put forward proposals to reform the Canadian constitution based on the notion of two equal nations as opposed to ten equal provinces.
1968 – He passed away on the 26th day of September of this year.
