Decker the Younger

Joseph Decker (31 December 1847 – 2 February 1920), known as Decker the Younger, was a French tailor, anarchist and syndicalist militant.

Born in Bas-Rhin, Decker became a tailor and was convicted of several offenses in his twenties before moving to Paris and joining the anarchist movement in the mid-1880s. He then integrated into numerous anarchist groups, such as The Panther of Batignolles, likely participated in actions supporting Clément Duval, and associated with other French anarchists of that period. Simultaneously, Decker became involved in trade union activities, particularly within the tailoring profession.

He continued his activism at least until the early 20th century.
