Michelozzo di Bartolomeo Michelozzi (1396 – 7 October 1472) was an Italian architect and sculptor. Considered one of the great pioneers of architecture during the Renaissance, Michelozzo was a favored Medici architect who was extensively employed by Cosimo de' Medici. He was a pupil of Lorenzo Ghiberti in his early years, and later collaborated with Donatello. Known primarily for designing Palazzo Medici Riccardi in Florence, he is often overshadowed by his contemporaries Donatello in sculpture and Brunelleschi in architecture. Life Early life Michelozzo was born in Florence in 1396. He was the son of Bartolomeo di Gherardo Borgognone and Antonia. Borgognone was of French origin and arrived in Florence from Burgundy at an unknown date. Borgognone lived and worked in the Santa Croce quarter of Florence as a tailor, and was made a Florentine citizen on 9 April 1376. Michelozzo had three brothers named Leonardo (b. 1389/90), Zanobi (b. 1391), and Giovanni (b. 1403). By 1391, Michelozzo's family had moved to the San Giovanni quarter, where they continued to live throughout his life. Little is known about Michelozzo's childhood, other than that he received a comprehensive education in reading, writing, and arithmetic, and that he began working as a die-engraver for the Florentine mint in 1410. As an engraver, Michelozzo learned how to cast, chase, and gild copper and bronze, two of the metals in which the Medieval and Renaissance goldsmith most commonly worked. He also gained immense precision of hand and a mastery of sculptural design in miniature. Beginning in the early 1420s, Michelozzo became a member of the Arte di Maestri di Pietra e Legname, one of the Guilds of Florence that represented the master stonemasons, wood-carvers, and sculptors. He later served as one of the consuls of the Guild in 1430. Throughout his life, Michelozzo retained the family residence on Via Larga, which was near the Medici Palace and next door to the humanist Bartolomeo Scala. In addition, Michelozzo possessed a house and garden in S. Domino a Brozzi. Michelozzo's father died sometime before 1427, and his mother passed sometime between 1433 and 1442. Apprenticeships Beginning in 1420, Michelozzo studied under Lorenzo Ghiberti. Michelozzo's first projects with Ghiberti was the North Door of the Baptistry between the years 1417 and 1423/4, in which Michelozzo's responsibilities "could only have been in the chasing and gilding of the panels, possibly in casting the four late reliefs...and in the frame....Most
