I don't know whether to name personal heroes/idols or famous folks, but I think of heroes as people who go out of their way and even put themselves at potential harm for others.

My personal ones would probably be my dad, my older sister, who was the most giving person I ever knew, and a fireman I once worked with, Lieutenant Kelly, who was quite literally the bravest, most courageous, noble guy I've ever known. He'd do anything to help others, and he risked his life to do so regularly.

Famous "pet" heroes? Probably Harriet Tubman. Cesar Chavez. Jimmy Carter. Che Guevara. Maybe Eleanor Roosevelt. And for their efforts toward civil rights, JFK, RFK and MLK.
