Who engineered the self-supporting dome of the Florence Cathedral?

The self-supporting dome of the Florence Cathedral, known as the Duomo, was engineered by Filippo Brunelleschi. He designed the dome in the early 15th century, employing innovative techniques and materials that allowed it to be constructed without the need for external supports. Brunelleschi's ingenious use of a double-shell structure and herringbone brick pattern contributed to its stability and aesthetic appeal. His work on the dome is considered a masterpiece of Renaissance architecture.
