Ernst Wilhelm Arnold von Hoeppner (14 January 1860 – 26 September 1922) was a Prussian cavalry officer who served as the Commanding General of the German Air Service (Luftstreitkräfte) during World War I. Hoeppner was born in Tonnin on the island of Wollin in Pomerania on 14 January 1860.

[1] He was the third son of a Prussian major[2] Ernst Ferdinand Hoeppner (1813-1881) and his wife Wilhelmine Minna, née Kropf (1827-1896).

Ernst Hoeppner attended the Cadet School in Potsdam from 1872 and in 1879 he was commissioned as a second lieutenant in the 6th Magdeburg Dragoon Regiment.

In September 1912 he was made commander of the 4th Cavalry Brigade in Bromberg[5] and the following year he was raised to the nobility by Kaiser Wilhelm II and granted the nobiliary particle von before his surname.

[6] Hoeppner reorganized the fragmented air services, greatly increasing the number of Jastas (squadrons) and forming them into Jagdgeschwader (wings).

The German War Ministry issued orders for Von Hoepppner's post to be disestablished on 16 January 1919 although he appears to have continued as Commanding General for a few more days.

Hoeppner returned to his estate at Groß-Mokratz (now Mokrzyca Wielka) on the island of Wollin in the Baltic Sea where he wrote his memoirs.
