Samuel Clemens, aka Mark Twain, and Harriet Beecher Stowe were not just contemporaries, they were neighbors:
By Elizabeth J. Normen for Connecticut Explored
When Mark Twain built his dream house in Hartford’s Nook Farm neighborhood in 1874, his next-door neighbor was Harriet Beecher Stowe, the most famous American woman in the world. Twain was on the verge of international fame and while living in Nook Farm wrote his most noteworthy books. Twain and Stowe brought unusual literary firepower to the neighborhood, but they took their place among an unusual enclave of citizens who were themselves well known on the national stage in politics and reform.
Twain described his first impressions of Nook Farm and Hartford in a letter to the San Francisco Alta California, January 25, 1868:
I am in Hartford, Connecticut, now…. I think this is the best built and handsomest town I have ever seen. … This is the centre of Connecticut wealth. Hartford dollars have a place in half the great moneyed enterprises of the union. All those Phoenix and Charter Oak Insurance Companies … are located here. The Sharp’s rifle factory is here; the great silk factory of this section is here; the heaviest subscription publishing houses in the land are here; and last and greatest, the Colt’s revolver manufactory is a Hartford institution.
The people who wrote Uncle Tom's Cabin and Huckleberry Finn were quite different in literary style, perspective and outlook:
Clemens was a product of the South.
Stowe never set foot in the South.
Uncle Tom was published before the Civil War.
Huckleberry Finn was published after the Civil War.
Stowe was a well known and outspoken abolitionist.
Clemens joined the Confederacy and then, apparently conflicted and ambivalent, removed himself from the 'War to end Slavery' and went to California.
As public figures, Stowe was forthright and forthcoming re her stand against slavery. By the time Clemens reached national status and acclaim, slavery had been abolished and he was silent on Jim Crow and segregation....
Though neither was an egalitarian, as between the two, Stowe appears to have been a stronger advocate of social justice...Clemens remained silent or low key on such matters...
Neither expressed the notion that black people should be deemed politically and socially equal to white people.
Clemens' characterization of Jim in "Huckleberry Finn" is such that he becomes an endearing and enduring figure whose qualities of compassion and courage draw readers close enough to understand and appreciate the fact that Jim is a human being.
However, Clemens chose to continually and constantly remind his readers that first, foremost and above all else, Jim is a 'nigger' and says as much not less than 219 times throughout the book...
Clemens' humanization of Jim as a prominent, if not the dominant, heroic figure is tempered and diminished by the author's continuous and repeated reference to Jim as being a 'nigger'.
Referencing specific or certain black people as "Auntie" or "Uncle" carried connotations of condescending endearment.
Lincoln referred to Sojourner Truth as "Auntie" meaning she was well liked and seen as posing no threat to the established order even though she worked feverishly against it during her time.
Harriet Beecher Stowe's 'Uncle Tom' is characterized as a heroic figure of courage and wisdom beyond his station....
Ironically, the appellation "Uncle Tom" is, today, a derogatory epithet and invective that denotes sycophantic cowardice by a black person in interactions and dealings with white people...
Quite the contrary, if not the direct opposite, of the heroic profile MS Stowe attempted to bestow upon her "Uncle Tom".
