Brief Biography-Lorenzo Ghiberti was initially a goldsmith and painter until 1403 when he won the competition to do bronze doors for the Baptistry of the Florence Cathedral. The first set took between 1403 and 1424, and the second was between 1425 and 1452. It was the principal undertaking of his career. The third set of doors, finished in 1452, was christened the Gates of Paradise by Michelangelo. In 1418 he built a model of the Cathedral’s dome, although his input into its construction is uncertain. He filled three niches of Or San Michele with bronze statues, Saint John the Baptist, Saint Matthew and the Tabernacle, and Saint Stephen. Notable students who worked in his studio were Donatello and painters Paolo Uccello and Masolino da Pinacle. Ghiberti wrote his autobiography in his Commentarii on art. He died in Florence 1455.
