Filippo di ser Brunellesco di Lippo Lapi, commonly known as Filippo Brunelleschi and also nicknamed Pippo by Leon Battista Alberti, was an Italian architect, designer, goldsmith, and sculptor. He is considered to be a founding father of Renaissance architecture. He is recognized as the first modern engineer, planner, and sole construction supervisor. In 1421, Brunelleschi became the first person to receive a patent in the Western world. He is most famous for designing the dome of the Florence Cathedral, and for the mathematical technique of linear perspective in art which governed pictorial depictions of space until the late 19th century and influenced the rise of modern science. His accomplishments also include other architectural works, sculpture, mathematics, engineering, and ship design. Most surviving works can be found in Florence.
