According to The Oxford Companion of Food and Drink, "the name presumably comes from the Thousand Islands between the United States and Canada in the St. Lawrence River." In the Thousand Islands area, one common version of the dressing's origins says that a fishing guide's wife, Sophia LaLonde, made the condiment as part of her husband George's shore dinner[when?]. Often in this version, actress May Irwin requested the recipe after enjoying it.[when?] Irwin in turn gave it to another Thousand Islands summer resident, George Boldt, who was building Boldt Castle in the area. Boldt, as proprietor of the Waldorf-Astoria Hotel, instructed the hotel's maître d'hôtel, Oscar Tschirky, to put the dressing on the menu.[when?] A 1959 National Geographic article states, "Thousand Island Dressing was reportedly developed by Boldt's chef."
