From UC Berkeley News:
Throughout his life, American writer and humorist Samuel Langhorne Clemens, better known by his pen name, Mark Twain, formed friendships with many notable figures in history that shaped his work and the way he saw the world.
A new multimedia project published by UC Berkeley’s Bancroft Library, “Six degrees of Mark Twain,” has pulled from a vast collection of the library’s Mark Twain Papers and Project — the largest collection of Twain’s private writings and manuscripts — to explore how Twain’s life intersected with six people: P.T. Barnum, Nikola Tesla, Helen Keller, Frederick Douglass, Harriet Beecher Stowe and Ulysses S. Grant.
The project includes personal letters and photos from Twain’s life, essays unpublished in Twain’s lifetime, excerpts from his autobiography, as well as audio and video commentary by Robert Hirst, general editor of the Mark Twain Papers and Project.
