Frederick Douglas is a well-known African American thinker, abolitionist and speaker.
In his celebrated memoir <em>Narrative of the life of Frederick Douglas</em>, he championed the rights of African-American slaves and was one of the leaders of the anti-slavery movement.
At one point in his life, he also worked as an adviser to Abraham Lincoln during the Civil War in America, and later became the first African-American to hold official political office.
