Sorry, hippies. Somebody beat you to it.

Justin Holland (1819-1887), was a civil-rights activist, moving around the same circles as Frederic Douglass. He worked with whites to free slaves in the Underground Railroad. Oh yeah, and he also played a mean guitar.

He became nationally known for his guitar method books – his approach to teaching was considered very conservative for the time (sorry, hippies; I guess he was a square). And, while not a composer himself, he was famous for arranging famous works of other composers, including this one, which includes some popular tunes from Carl Maria von Weber‘s opera, Oberon.
