(1378 - 1455) A Florentine sculptor and goldsmith who taught both Donatello and Filippo Brunelleschi. He is best known for two pairs of bronze doors on the Florence Baptistery (associated with the Duomo, or Florentine Cathedral). He produced a single, low-relief panel to win a 1401 competition (defeating Brunelleschi) for the commission to design the 28 panels for the north doors. After that, he was given another commission to design ten panels for the east doors. This latter work, by far his most famous, was dubbed the 'Gates of Paradise' by Michelangelo.
