Gottfried Christian Voigt (1740–1791) was an 18th century German scholar, author of a 1791 "History of Quedlinburg Abbey" (Geschichte des Stifts Quedlinburg)
He is known as the source of the estimate of "nine million victims" in the European witch-hunts which became an influential popular myth in 20th century feminism and neopaganism. The history of this estimate was researched by Behringer (1998)[1]. Voigt published it in a 1784 article, writing in the context of the Age of Enlightenment, wishing to emphasize the importance of education in rooting out superstition and a relapse into the witch-craze which had subsided less than a lifetime ago in his day. He was criticizing Voltaire's estimate of "several hundred thousand" as too low.
