On June 21, the New York Yankees announced Gehrig's retirement and proclaimed July 4, 1939, "Lou Gehrig Appreciation Day" at Yankee Stadium. Between games of the Independence Day doubleheader against the Washington Senators, the poignant ceremonies were held on the diamond. In its coverage the following day, The New York Times said it was "Perhaps as colorful and dramatic a pageant as ever was enacted on a baseball field [as] 61,808 fans thundered a hail and farewell". Dignitaries extolled the dying slugger and the members of the 1927 Yankees World Championship team, known as "Murderer's Row", attended the ceremonies. New York Mayor Fiorello La Guardia called Gehrig "the greatest prototype of good sportsmanship and citizenship" and Postmaster General James Farley concluded his speech by predicting, "For generations to come, boys who play baseball will point with pride to your record."
