William Harker

William Harker was a 19th-century American slave trader, known for his extensive career spanning over two decades. Operating primarily in Maryland, Harker played a significant role in the domestic slave trade, actively engaging in the buying and selling of enslaved African Americans from 1835 to 1859. His longevity in the trade was notable during a time when many slave traders came and went.

Stowe highlighted Harker's business practices, particularly his focus on the profitability of the Southern market:
