Founding member and former president of the Community Service Organization (CSO), Anthony (Tony) P. Rios gained attention in 1952 when he and Alfred Ulloa were exonerated of interfering with police in a brutality case. The two men had attempted to protect a man from being beaten by a drunken police officer, and ended being beaten and detained themselves. From its conception in 1947, the state-wide Community Service Organization (CSO) fostered a mission to the Mexican-American community to serve as a grassroots organization promoting empowerment. The organization was founded and grew through the efforts of Fred Ross, Edward Roybal, Dolores Huerta, Cesar Chavez, Herman Gallegos, and Anthony (Tony) Rios, under the auspices of Saul Alinsky's Industrial Areas Foundation (IAF). 11 in. x 8.5 in.
