While in the midst of researching Mark Twain's autobiography, I just noticed that yesterday, Sunday, was the 100th anniversary of Charles Neider's birth on January 18, 1915. Neider, as I'm sure most of you know published _The Autobiography of Mark Twain_ in 1959, arranging the material in an approximation of a cradle-to-grave narrative that differs greatly from the new University of California Press edition of the same material. Neider's version is still in print (at least in a Kindle edition) and has probably been read by more people than any other edition. Neider died in 2001. Though almost forgotten today, he had an enormous impact on Mark Twain studies and on public perceptions of Mark Twain through the numerous volumes of Mark Twain's stories, sketches, essays, novels, letters, and speeches that he edited. Among those volumes is _The Complete Short Stories of Mark Twain_ (first published in 1957 and still available in a Kindle edition), which is almost certainly the most widely read collection of Mark Twain's stories ever published. While we should thank Neider for helping to keep Mark Twain's name alive through such books, we must also regret has lapses, such as including the editorial fraud "The Mysterious Stranger" in his short story collection. I’ll end this note by acknowledging that Neider’s collections of Mark Twain’s stories, sketches, and essays played an important role in drawing me into Mark Twain studies. I don’t know whether that fact should be placed in his credit column or his debit column, but wherever he is now, I’ll wish him a happy birthday.
