Meissner, Georg (1829–1905), German anatomist and physiologist. Meissner conducted in 1851 intensive comparative microscopic investigations on the fibers and cells of the common trunk of the vestibular and cochlear nerves. In 1852 he studied the tactile corpuscles of the skin which now bear his name. He published other papers dealing with the problems of microscopy, particularly those relating to the skin. In 1857 he published a description of the nerve plexus in the submucosa of the intestinal wall.
