Born at
Colmar (now in the
département of
Haut-Rhin), he became president of the local order of
lawyers, and in 1789 was elected as a deputy to the
Estates-General by the
Third Estate of the
bailliage of Colmar-Schlestadt. In the
National Constituent Assembly his
oratory, legal knowledge and austerity of life gave him much influence. A partisan of revolutionary reforms, Rewbell voted in favor of reforms such as the
Civil Constitution of the Clergy, but opposed the recognition of
citizenship rights for
Alsatian Jews. In July 1791, after the
flight of
Louis XVI, the
constitutional king, Rewbell left the
Jacobin Club and joined the
Feuillants. During the session of the
Legislative Assembly, after the Constituent Assembly was dissolved in September of that year, he exercised the functions of
procureur syndic, and was subsequently secretary-general of the
département of Haut-Rhin. He was elected to the
Republic's National Convention in 1792, and was its envoy to the
Rhineland, advocating the union of the
Electorate of the Palatinate and other territories with France. A zealous promoter of the
Trial of Louis XVI, he was absent on mission at the time of the king's condemnation. ==Directorate and retirement==
