Orso Mario Corbino (30 April1876, Augusta – 23 January1937, Rome) was an Italianphysicist and politician. He served as the minister for education in 1921 and as the minister for economy in 1921. He also served as professor in Messina (1905) and in Rome (1908). Noted for his studies of the influence of external magnetic fields on the motion of electrons in metals and discovered the Corbino effect. Corbino worked with Damiano Macaluso where they discovered the Macaluso-Corbino effect, a strong magneto-rotation of the plane of polarization observed at wavelengths close to an absorption line of the material through which the light is travelling.
