History

From Wikipedia:

There are conflicting accounts as to the origin of Eggs Benedict, including: In an interview recorded in the "Talk of the Town" column of The New Yorker in 1942, the year before his death, Lemuel Benedict, a retired Wall Street stock broker, claimed that he had wandered into the Waldorf Hotel in 1894 and, hoping to find a cure for his morning hangover, ordered "buttered toast, poached eggs, crisp bacon, and a hookerof Hollandaise." Oscar Tschirky, the famed maître d'hôtel, was so impressed with the dish that he put it on the breakfast and luncheon menus but substituted ham for the bacon and a toasted English muffin for the toast.
