I read an interesting book. THE PROFESSOR AND THE MADMAN: A TALE OF MURDER, INSANITY, AND THE MAKING OF THE OXFORD ENGLISH DICTIONARY (Simon Winchester) tells the story about the making of the famous reference book. One of the most prolific contributors was an American ex-Civil War surgeon who lived in an insane asylum for decades after murdering an innocent man. If that’s not enough, consider the fact that he cut off his own penis to relieve himself of all kinds of sexual anxiety.
