Jean-Baptiste Massieu
French politician
Jean-Baptiste Massieu (17 September 1743 Pontoise - 8 June 1818 Brussels) was a French bishop, politically active during the French Revolution.
The son of a Norman hosier, he took holy orders in Rouen, took up his first post as a teacher of rhetoric at Vernon and in 1768 moved to the royal college in Nancy. He may also have been a tutor to the younger Lameth brothers, and in 1782 was appointed curate of Cergy.
When the Estates General were summoned, he was elected to sit for the First Estate representing Senlis. In December 1789 he became secretary of the new National Assembly and joined the ecclesiastical committee, and in December 1790 he took the oath to the Civil Constitution of the Clergy. He was elected constitutional bishop of Oise on 21 February 1791.
On 4 September 1792 he was elected to represent Oise in the National Convention, receiving 315 out of 627 votes. During the trial of Louis XVI he voted against appeal to the people, for the death penalty and against reprieve. In 1793 he was sent as a representant en mission first to Ardennes and then to Marne. He renounced his religious vows while he was away from Paris, and shortly afterward married the daughter-in-law of the mayor of Givet, Marie-Odile Briquelet.

Why this record matters

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated May 25, 2026. The linked authority identifier is Q3164267. VIAF identifies the subject as 49334416. The Library of Congress control number is nr2001007099. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1743, 1818, 1768 and 1782.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
