Born in Haimhausen, Bavaria, Eckartshausen studied philosophy and Bavarian civil law in Munich and Ingolstadt.

He was the author of The Cloud upon the Sanctuary, a work of Christian mysticism which was later taken up by occultists.

Translated into English by Isabelle de Steiger, the book was given a high status in the Hermetic Order of the Golden Dawn, particularly by Arthur Edward Waite.

It is known to have attracted English author and the founder of Thelema, Aleister Crowley, to the Order.

"[2] Von Eckartshausen was acquainted with Johann Georg Schröpfer, an early pioneer of phantasmagoria, and himself experimented with the use of magic lanterns to create "ghost projections" in front of an audience of four or five people.
