🍔 Who Invented the Hamburger?

Updated July 2026

Ask who invented the hamburger and you won't get one answer — you'll get several, each with passionate local supporters. The honest truth is that the origin of the American hamburger sandwich is disputed and probably unknowable, because ground-beef patties and bread were both common long before anyone thought to document putting them together. Here are the claims most often cited, presented as competing accounts rather than settled history.

Why the question has no clean answer

The core problem is documentation. Ground or chopped beef has an ancient history, and "Hamburg steak" — a seasoned beef patty named after Hamburg, Germany — appears on American menus in the 1800s. The leap that people argue about is when someone first served that patty in or between bread as a portable sandwich. That moment happened at fairs, lunch counters and food stands where nobody was keeping records, so several people can each plausibly claim to have done it first.

Louis Lassen / Louis' Lunch (New Haven, Connecticut)

One of the best-known claims credits Louis Lassen of Louis' Lunch in New Haven, Connecticut, commonly said to have served a beef patty between slices of toast around 1900. The establishment still operates and still serves burgers on toast. Supporters point to this continuity; skeptics note that "between toast" differs from the bun-based hamburger and that the earliest dating relies on later recollection.

Charlie "Hamburger Charlie" Nagreen (Seymour, Wisconsin)

Another account holds that Charlie Nagreen, known as "Hamburger Charlie," flattened a meatball between bread at the Seymour Fair in Wisconsin (a date of 1885 is often cited) so fairgoers could walk and eat. Seymour celebrates this story and bills itself as a home of the hamburger. As with the others, the early date rests largely on local tradition rather than contemporary documents.

Fletcher "Old Dave" Davis (Athens, Texas)

Boosters in Athens, Texas credit Fletcher Davis with selling a ground-beef sandwich at his lunch counter, and suggest he brought it to the 1904 St. Louis World's Fair, where the hamburger gained national attention. The link to the Fair is part of the appeal of this claim, though the evidence connecting Davis specifically to it is circumstantial.

The Menches brothers (Ohio / Erie County, New York)

The Menches brothers, traveling fair vendors, are credited in another account with improvising a beef sandwich (a date of 1885 at the Erie County Fair in Hamburg, New York is often cited) when they ran short of an ingredient. Their descendants have kept the story alive. It is one more plausible "first," which is exactly the problem — several are plausible.

What we can actually say

What historians can say with confidence is narrow: the Hamburg steak preceded the sandwich; the hamburger became a national food after gaining exposure around the early 1900s, including at the 1904 St. Louis World's Fair; and no single inventor can be proven. The most accurate answer to "who invented the hamburger" is "it's disputed" — the sandwich emerged from many hands rather than one.
