Mario Savio (December 8, 1942 – November 6, 1996) was an American activist and a key member in the Berkeley Free Speech Movement.
He is most famous for his passionate speeches, especially the "put your bodies upon the gears" address given at Sproul Hall, University of California, Berkeley on December 2, 1964.
Savio remains historically relevant as an icon of the earliest phase of the 1960s counterculture movement.
