Jakob Christoph Heer (17 July 1859, Winterthur – 20 August 1925, Zürich) was a Swiss novelist and travel writer.
He originally worked as a "vicar" (substitute teacher) in Glattfelden then, in 1882, found a permanent position in Dürnten.
An heiligen Wassern (On Holy Waters) was filmed in Germany in 1932 by Erich Waschneck, under the title Stürzende Wasser (Sacred Water), and again in 1960 by the Swiss director, Alfred Weidenmann (An Heiligen Wassern).
On a hill in Winterthur, there is a "Gedenkstein" (commemorative stone), donated by the city of Poschiavo.
He had originally wanted to be buried in another location closer to town but, by the time he died, a slaughterhouse was being built near there.
