Ralph DiGia (December 13, 1914 – February 1, 2008) was a World War II conscientious objector, lifelong pacifist and social justice activist, and staffer for 52 years at the War Resisters League. Born in the Bronx to a family of Italian immigrants (his father was an anarchist barber) in 1914, DiGia grew up on Manhattan's Upper West Side. A 1927 rally for Italian anarchists Nicola Sacco and Bartolomeo Vanzetti set him on the path he would follow for 80 years.
