This article cites information which is factually in error. i.e., Paul Morphy was targeted in a 1860s-80s campaign of stalking. Attempts by friends of Morphy vouching for his sanity & to stop such false rumors (New Orleans Republican 11/21/1875; Tennessean Nashville, 5/05/1877, “The Truth About Mr. Paul Morphy. He has Never been Insane”; Detroit Free Press 11/30/1880, etc). How many other "facts" are based on idle rumors by jealous chess rivals? (https://century-in-chess.blogspot.com)
