Catholic Radical Alliance
The Catholic Radical Alliance was founded in Pittsburgh, Pennsylvania, in 1937 by the Roman Catholic priests Charles Owen Rice, Carl Hensler, and George Barry O'Toole, with the approval of their bishop, Hugh C. Boyle. It supported the unionization of workers in the H. J. Heinz Company and the Loose Wiles Biscuit Company in Pittsburgh.
