Brunelleschi, Filippo, broon uh LEHS kee, fih LIHP oh (1377?-1446), was the first important architect of the Italian Renaissance. He developed techniques for lifting construction materials into position and for creating domes. Brunelleschi designed and supervised the raising of the dome over the Cathedral of Florence. Brunelleschi's study of classical Roman architecture influenced his many noted buildings in Florence. They include the church of Santo Spirito and the Pazzi Chapel.
