Harriet Elisabeth Beecher Stowe (1811 – 1896) was an American abolitionist and author.
She came from the Beecher family, a famous religious family, and is best known for her novel Uncle Tom’s Cabin (1852), which depicts the harsh conditions for enslaved African Americans.
The book reached millions as a novel and play, and became influential in the United States and Great Britain, energizing anti-slavery forces in the American North, while provoking widespread anger in the South.
