Friedrich Heinrich Bidder (November 9, 1810 - August 22, 1894) was a German physiologist and anatomist who was a native of Latvia. In 1834 he received his doctorate from the University of Dorpat, where he became a professor of anatomy (1842), and physiology and pathology (1843).
Bidder is primarily remembered for his studies of nutrition and gastric physiology. From 1847 to 1852 he performed physiological-chemical studies of digestive juices and metabolism with chemist Carl Ernst Heinrich Schmidt (1822-1894). Bidder also performed important research involving the sympathetic nervous system with Alfred Wilhelm Volkmann (1801-1877).
Bidder's name is associated with two anatomical structures:
- Bidder's ganglia: Ganglia located at the lower end of the atrial septum; sometimes called the ventricular ganglia.
- Bidder's organ: A spherical, brownish reproductive organ of male toads.
