Saturday is the birthday of Cesar Chavez, who founded and led the massively influential United Farm Workers of America. In California, some government offices will be closed today (Friday) or Monday.

Chavez -- born March 31, 1927 — is credited with ending widespread discriminatory practices against Hispanics in America, particularly in California during the 1960s and ’70s. He often used the slogan “Si, se puede,” which is Spanish for: “Yes, it can be done.”

The Navy veteran and labor leader, who died in 1993, also famously mobilized thousands of migrant farmworkers. The action promoted and achieved union contracts and labor rights for field workers. Chavez faced death threats throughout his life.
