Detractors of the Louis' Lunch claim include Josh Ozersky, a food editor for New York Magazine. In Ozersky's book, "The Hamburger: A History", Ozersky denies the claim based on the definition of a hamburger and told the "New Haven Register", "If you say it can be on toast, you're essentially redefining the hamburger out of existence. The hamburger as the world knows it means a sandwich of ground beef on a bun." However, Motz's "Hamburger America" notes that the hamburger bun did not exist in 1900 nor did so for another 20 years. Ozersky's book also notes earlier claimants and recognizes Walter Anderson for creating the modern hamburger.
