It's recognized as one of the most noted moments in the civil rights movement.
The year was 1960 when a young Ruby Bridges walked up the stairs into William Frantz Elementary in New Orleans. This seemingly ordinary act was in fact, historic, as Ruby and three other girls were the first African Americans to integrate all-white schools in New Orleans.
The term integrate means to bring people together, usually of different races or religions, and to provide them with equality in society or an organization.
This week, Ruby, her teacher and the federal officer who kept them safe reunited to talk about the historic moment.
