César

Born in 1927 in Yuma, Arizona, César Chavez lived the hard-scrabble life of a migrant worker during the Depression. Although his mother wanted him to get an education, César left school after eighth grade to work. He grew to be a charismatic leader and founded the National Farm Workers Association, an organization that fought for basic rights for farm workers. In powerful poems and dramatic stylized illustrations, Carmen T. Bernier-Grand and David Díaz pay tribute to Chavez's legacy helping migrant workers improve their lives by doing things by themselves for themselves.
