(d Florence, 1366). Florentine painter, the son of a painter and mosaicist Gaddo Gaddi (dc.1330). According to Cennino Cennini, Taddeo was Giotto's godson and worked with him for 24 years. He was one of the leading Florentine artists of his day and in 1347 he headed a list of the best living painters made for the purpose of choosing a master to paint an altarpiece for S. Giovanni Fuorcivitas, Pistoia. His best-known works were painted for S. Croce, Florence, notably the frescos devoted to the life of the Virgin in the Baroncelli Chapel (c.1330), and the panels illustrating the life of Christ (c.1335), originally meant for the doors of a sacristy cupboard and now scattered among museums in Florence (Accademia), Munich (Alte Pin.), and Berlin (Gemäldegalerie).
