New York Times of Jan 11, 1859:
The greatest excitement prevailed, and an arrangement was made by which the game was kept on three boards at the Café de la Régence (only a few blocks distant), a domestic carrying the moves every half hour. Thus the large crowd collected at the Café were enabled to follow the progress of the game. The game was commenced in the presence of Messrs. Lequesne, of the Institute, De Saint-Amant, Arnous de Riviere, Journoud, Prete [sic], Carlini, F. Edge, Jams. Mortimer, and your correspondent, all invited especially by Messrs. Morphy and Anderssen as witnesses for the game.
