When Carver Clark Gayton was growing up in Seattle in the 1940s he didn’t hear anything about African-American history in school. But his mother told him stories, including one about his great-grandfather Lewis George Clarke.
Clarke was an escaped slave and an abolitionist. His personal story found its way into the anti-slavery novel "Uncle Tom’s Cabin" that went on to become the second most popular book in the 19th century. It’s seen as one of the causes of the Civil War.
