a small lunch wagon in New Haven, Connecticut, is said to have sold the first hamburger and steak sandwich in the U.S. in 1900. New York Magazine states that "The dish actually had no name until some rowdy sailors from Hamburg named the meat on a bun after themselves years later," also noting that this claim is subject to dispute. A customer ordered a quick hot meal and Louis was out of steaks. Taking ground beef trimmings, Louis made a patty and grilled it, putting it between two slices of toast. Some critics like Josh Ozersky, a food editor for New York Magazine, claim that this sandwich was not a hamburger because the bread was toasted. Charlie Nagreen One of the earliest claims comes from Charlie Nagreen, who in 1885 sold a meatball between two slices of bread at the Seymour Fair now sometimes called the Outagamie County Fair. The Seymour Community Historical Society of Seymour, Wisconsin, credits Nagreen, now known as "Hamburger Charlie," with the invention. Nagreen was fifteen when he reportedly sold pork sandwiches at the 1885 Seymour Fair, made so customers could eat while walking. The Historical Society explains that Nagreen named the hamburger after the Hamburg steak with which local German immigrants were familiar. Otto Kuase According to White Castle, Otto Kuase was the inventor of the hamburger. In 1891, he created a beef patty cooked in butter and topped with a fried egg. German sailors would later omit the fried egg. Oscar Weber Bilby The family of Oscar Weber Bilby claims the first-known hamburger on a bun was served on July 4, 1891, on Grandpa Oscar's farm. The bun was a yeast bun. In 1995, Governor Frank Keating proclaimed that the first true hamburger on a bun was created and consumed in Tulsa, Oklahoma in 1891, calling Tulsa, "The Real Birthplace of the Hamburger." Frank and Charles Menches Frank and Charles Menches claim to have sold a ground beef sandwich at the Erie County Fair in 1885 in Hamburg, New York. During the fair, they ran out of pork sausage for their sandwiches and substituted beef. The brothers exhausted their supply of sausage, so they purchased chopped-up beef from a butcher, Andrew Klein. Historian Joseph Streamer wrote that the meat was from Stein's market, not Klein's, despite Stein's having sold the market in 1874. The story notes that the name of the hamburger comes from
