Taddeo Gaddi, the son of Gaddo di Zanobi, called Gaddo Gaddi, had been a member of Giotto's workshop from 1313 to 1337, when his master died.

His principal work is the cycle of Stories of the Virgin in the Baroncelli Chapel of the Basilica of Santa Croce in Florence (1328–1338).

Later he perhaps paints the cabinet tiles in the sacristy of the same church, now divided among the Galleria dell'Accademia of Florence and museums in Munich and Berlin.

These works show his mastership of Giotto's new style, to which he has added a personal experimentation in the architectural backgrounds, such as in the staircase of the Presentation of the Virgin in the Baroncelli Chapel.
