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.
In 1951, DiGia, Dellinger, Sutherland, and fellow CO Art Emery bicycled from Paris to Vienna, handing out antiwar leaflets as they went, urging Cold War soldiers everywhere to lay down their arms and refuse to fight.
[2] In the early 1950s, he left the commune and moved to the Manhattan area that would later be called Soho, where he lived for the rest of his life, and in 1955 he joined the War Resisters League staff as a bookkeeper.
In 1998, he was arrested in Washington at WRL's "A Day Without the Pentagon" in 1998 and at the mass protests against the acquittal of the New York City police officers who shot Guinean immigrant Amadou Diallo in 1999.
In 1996, the Peace Abbey, the multifaith retreat center in Sherborn, Massachusetts, gave DiGia its Courage of Conscience award "for his example as a conscientious objector and for over forty years of dedicated service at the War Resisters League."
In 2005, WRL gave the 40th annual War Resisters League Peace Award to DiGia and his longtime colleague, former photographer Karl Bissinger.
