According to a fairly trustworthy source:
"Isidor Arthur Gunsberg (November 2, 1854 – May 2, 1930) was a chess player, best known for narrowly losing the 1891 World Chess Championship match to Wilhelm Steinitz."
"In the late 1880s and early 1890s Gunsberg was one of the top players in the world. Arpad Elo calculates that Gunsberg's best 5-year average Elo rating was 2560."
"In 1916 he sued the Evening News for libel when they said that his chess column contained "blunders". He won the suit after the British High Court accepted a submission that in chess matters, eight oversights did not make a "blunder"."
To celebrate this little-known chess master on this Memorial Day 2013, here is one of his finest games. Enjoy!
