Roberto de' Rossi was an early humanist in Florence,[1] a follower of Coluccio Salutati and, as the first pupil of Manuel Chrysoloras, one of the first Florentines to read Greek. Roberto de' Rossi was a wealthy patrician who never married and avoided public office but devoted his life to books and his studies in his house and garden in the Oltr'Arno district of Florence.[2] His translations of Aristotle and other classical Greek writers made them widely available to the Latin-reading public, but his modern claim to fame is as the tutor of Cosimo de' Medici, a role for which he was selected by Giovanni di Bicci. Roberto's friends Leonardo Bruni and Niccolo Niccoli were inherited by Cosimo and formed part of his circle.
