Spoiler Alert!
Abraham Lincoln reputedly took the diminuative author aside when introduced to her and asked, rhetorically, "Is this the little lady who started this big war?" Her husband was a firebrand abolitionist and Protestant Minister. Anti-slavery settlers in Kansas called their rifles "Beecher's Bibles". There was a shooting war in Kansas (see Jayhawks and Bushwackers) going on before the Civil War over the issue of slavery.
She was the author of the novel "Uncle Tom's Cabin" (See my graphic above.) Published in 1852, the novel had a profound effect on attitudes toward African Americans and slavery in the U.S. and is said to have "helped lay the groundwork for the Civil War". Uncle Tom's Cabin was the best-selling novel of the 19th century and the second best-selling book of that century, following the Bible. In the first year after it was published, 300,000 copies of the book were sold in the United States; one million copies in Great Britain.
Thank you very much! I have read a lot about that novel but have not read it yet. Did not memorize the name of the author.
