Jean-Gaspard Heilmann[needs German and French IPA] (c. 1718 – 27 September 1760) was an 18th-century French painter, author of popular landscapes, historical scenes and fine portraits.

[1] He was the first Mulhouse painter who enjoyed a certain notoriety in Paris.

[2] Born in Mulhouse, from a Mulhouse family documented since the 16th century,[3] an orphan at a very young age, he was formed in Schaffhausen by the painter Hans Deggeller, then at Basel (Switzerland).

Noticed by the cardinal of Tencin,[4] he followed him to Rome and executed many commissions for him.

[5] Heilmann lived there until his death and connected with the engraver Jean-Georges Wille and François Boucher, first painter of king Louis XV.
