Corti, Alfonso Giacomo Gaspare (1822–1876), Italian anatomist. Corti is remembered for his pioneering investigations of the mammalian cochlea. Inspired by the color effect of chromic acid solutions, which were used as fixing agents, he introduced carmine staining into microscopic anatomy. This method enabled Corti to distinguish and describe the individual components of the membranous cochlea. A number of these components including the organ of Corti, the tunnel of Corti, and the rods of Corti are now identified with his name. Corti published his research in 1851.
