Ramón y Cajal, Santiago (säntyäˈgō rämōnˈ ē kähälˈ) [key], 1852–1934, Spanish histologist. He was a university professor at Valencia (1881–86), at Barcelona (1886–92), and at Madrid (1892–1922), where he founded the Cajal Institute. He described the terminal branchings of neurons, devised a method of staining nerve tissues, and made numerous discoveries in the structure of the nervous system. For this work he shared with Camillo Golgi the 1906 Nobel Prize in Physiology or Medicine. His works include Studies of the Degeneration and Regeneration of the Nervous System (tr. 1928) and the classic Histology (tr. 1933).
