Joseph-Alfred Mousseau
Canadian politician (1837-1886)

Joseph-Alfred Mousseau (July 17, 1837 – March 30, 1886), was a Canadian lawyer and politician, who served in the federal Cabinet and also as the sixth premier of Quebec.
Biography
He was born in Sainte-Geneviève-de-Berthier, Lower Canada, the son of Louis Mousseau, the son of Alexis Mousseau, and Sophie Duteau, dit Grandpré. Mousseau was first elected to the House of Commons of Canada as a Conservative Member of Parliament in the 1874 election for the riding of Bagot, and was re-elected three times. In 1880, he was elevated to the Cabinet of Prime Minister Sir John A. Macdonald, serving first as president of the Queen's Privy Council of Canada, and then as Secretary of State for Canada.
Exchanging places with Joseph-Adolphe Chapleau, Mousseau left federal politics to become the sixth Premier of the province of Quebec from July 31, 1882. He served until his resignation on January 22, 1884, after being appointed as a puisne judge of the Superior Court for the district of Rimouski. He died in Montreal in 1886.
His brother Joseph Octave Mousseau was also a member of the Canadian House of Commons.

This brief starts where responsible research should: with the source description of “Joseph-Alfred Mousseau” as canadian politician (1837-1886). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as canadian politician (1837-1886). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Jul 30, 2026. The linked authority identifier is Q718557. VIAF identifies the subject as 18719522. The Library of Congress control number is n86838980. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1837, 1886, 1874 and 1880.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
