Jacques Démoulin (7 December 1905, in Bohain – 29 November 1991, in Acquigny),[1] was a French ballet dancer and painter.

After a few roles, he discovered dance thanks to Anna Stephann and left the theater to devote himself to a career as a dancer.

He remained at the Opera for 13 years, while continuing his work as a painter and press illustrator.

He met many personalities of Arts and Letters such as Picasso, Louis Leiris, Picabia and especially H. D. Kahnveiller with whom he spent his holidays.

In 1953, while on vacation in Morbihan, he discovered the burial mounds of Gravrini (-3000 BC) and in particular the engraved stones, which would notoriously influence his work for many years.
