César Chávez's birthday on March 31 gets the state holiday treatment in Colorado, California and Texas, and President Obama has called for Americans to observe the labor-rights and Latino icon's memory on that day.

Let's remember him on this day and check out the story of Chávez's life in farmworker advocacy -- in photographic shorthand.
