Joseph-Théodore Deck (2 January 1823 – 15 May 1891) was a 19th-century French potter, an important figure in late 19th-century art pottery.
Born in Guebwiller, Haut-Rhin, he began learning the trade in his early 20s, moving to Paris at age 24.
Several important figures from the next generation were trained by Deck, including Edmond Lachenal.
[1] In the 1880s he also worked in the Chinese pottery tradition, also collaborating with Raphaël Collin, and other artists of the time.
In 1887 he published a treatise under the title La Faïence, which is available in facsimile online.
