Moritz Schiff (28 January 1823, Frankfurt – 6 October 1896, Geneva) was a German physiologist and the elder brother of the chemist Hugo Schiff (1834-1915), particularly known for his staining technique.
He made major contributions to human physiology, including studies of the circulatory system and the action of the vagus nerve.
Unfortunately despite his independent and original spirit and being a much-cited author, he never reached the popularity of his contemporaries Emil du Bois-Reymond, Hermann von Helmholtz and Charles-Édouard Brown-Séquard.
