Filippo Brunelleschi was an influential Italian architect and engineer during the Renaissance. His most famous work was completing the dome of Florence Cathedral between 1420-1436, which was a revolutionary feat of engineering at the time. To build the dome, Brunelleschi invented new construction technologies and studied classical Roman architecture. He is also credited with inventing clocks and construction machinery that helped raise bricks for the dome. Brunelleschi's dome became one of the greatest architectural achievements of the Renaissance and remains a symbol of Florence.
