Jean Louis Thevenet was a French porcelain painter active from 1741 to 1777. Formerly a fanmaker, he painted flowers, both singular and in bunches. His early work included painting on porcelain in the studio of Louis François Gravant. He worked at Manufacture de Vincennes before joining Sèvres in 1756 where he was known as No. 121. His mark resembles a pin, although it has also been illustrated as a comma or musical note. He was known to still have painted in 1778, and to have had a daughter who also painted for Sèvres.
