Wilhelm Zimmermann (2 January 1807 in Stuttgart – 22 September 1878 in Mergentheim) was a German theologian and historian.

In 1850, Zimmermann was dismissed from his position as a teacher at the Oberrealschule because of his participation in the revolution of 1848-1849 and because of his caucusing with the Left wing in the Frankfurt Assembly.

[4] From 1841 to 1843, he published the 3-volume Allgemeine Geschichte des großen Bauernkrieges (General History of the Great Peasant War).

[5] The book argued that Europe had fallen in moral and physical decline because people had broken the "laws of nature" by consuming meat, overdressing and treating disease with poisons.

The book introduced German readers to ancient and modern vegetarian literature.
