Paul Grützner
Paul Grützner was a German physiologist born in Festenberg, Silesia.
He studied medicine at the universities of Würzburg, Berlin and Breslau, where he was a pupil of Rudolf Heidenhain. After graduation, he was an assistant at the physiological institute in Breslau. In 1881 he became a professor at the University of Bern, and in 1884 succeeded Karl von Vierordt at the physiological institute at the University of Tübingen.
Grützner performed numerous studies involving the physiology of nerves and muscles, circulatory physiology, glandular and gastric secretions, et al. In the 1870s, with Wilhelm Ebstein, he performed important research involving the physiochemical behavior of pepsin in the digestive tract. Findings from their research were published in an 1874 treatise called Ueber Pepsinbildung im Magen, and was included in.
Grützner is credited with introducing a colorimetric method for determining the quantity of pepsin in a solution. Among his numerous written articles was an 1879 physiological study on voice and speech titled Physiologie der Stimme und Sprache.
