Galileo

Galileo Galilei was an Italian physicist, mathematican, astronimer and philospher who played the first role in

Scientific Revolution. He droped two balls from the top of leaning Tower of Pisa in Italy in the episode "Ants in Arthur's Pants" to prove that gravity affects two differently sized objects equally. He was also mentioned in "Dad's Dessert Dilemma" where the class threw a party to celebrate his birthday. He was also mentioned in "Arthur's Treasure Hunt" when Arthur imagined Galileo's father making him go to bed because he stayed up too late discovering moons of Jupiter.
