Brunelleschi, and the Key to the Great Dome.

It took many different types of skills for the great artist, Fillipo Brunelleschi, to construct his dome. But, I think the main reason the Florence Cathedral Dome was a sucess was because of Brunelleschi's risk taking. His whole plan was a risk that many thought was sure to fail, but if he didn't take the risk of his design, then the dome could never had been built. The great builder also took a risk to travel to Rome for inspiration and ideas while his competeters could have taken his jobs. Brunelleschi's idea on building an inner and outter dome could not have happened if he hadn't had trusted himself and took that huge risk of complete failure.
