José Datrino, known as prophet Gentileza (11 April 1917 – 28 May 1996) was a Brazilian urban personality, kind of a preacher, who became known from 1980 by making quirky inscriptions under an overpass in Rio de Janeiro, where he walked in a white robe and long beard.
"Gentileza gera gentileza" ("Kindness begets kindness") is his most famous phrase.
