According to Wikipedia: "Albert Bigelow Paine (10 July 1861 – 9 April 1937) was an American author and biographer best known for his work with Mark Twain. Paine was a member of the Pulitzer Prize Committee and wrote in several genres, including fiction, humour, and verse... Paine wrote several children's books, the first of which was published in 1898. For a time he served as an editor of St. Nicholas Magazine, a leading children's periodical of the time. He went on to write about his travelling adventures, including The Tent Dwellers, written about a trout fishing trip to Nova Scotia. His 1901 book The Great White Way written about the Arctic indirectly gave New York City's Broadway the name "Great White Way" He was the official biographer and literary executor for Mark Twain, and worked with him (and on his behalf after his death) on various projects. His work on Twain's unfinished story The Mysterious Stranger saw him combine three versions of the story into one."
