Johann Peter von Langer

His father, Anton Langer (1721–1788), was the gardener for the Hatzfeld family at their estate surrounding Schloss Kalkum [de].

[1] In 1794, when the War of the First Coalition brought a halt to activities at the academy, he and his family moved to Duisburg, where he and the entrepreneur, Johann Böninger (1756–1810), created the "Mechanographische Institut"; producing flower- and figure-patterned wallpaper.

In 1801, after the Treaty of Lunéville redrew France's borders, Böninger moved the factory to Paris to avoid the new import taxes.

Langer returned to Düsseldorf, where he helped resurrect the academy and once more took up his position as director, with special attention to the art gallery.

He retained his position as director until his death in 1824 and was succeeded by Peter von Cornelius His paintings were mostly religious in nature.
