The country that had hamburgers first is the United States.
The United States is who created the modern hamburger sandwich as we know it today.
Although Germany was also the origin of the Hamburg Steak which is a patty of chopped beef.
Several different American individuals and even locations in the late 1800s are also credited with putting ground beef patties between two slices of bread or a bun for the first time, which gives us the hamburger that we know and love today.
Fletcher Davis of Athens, Texas is also believed to have sold his hamburger sandwich in the late 1880s, later bringing it to the 1904 St. Louis World's Fair.
And Charlie Nagreen of Wisconsin also sold a hamburger steak between two slices of bread at a fair in 1885.
Frank and Charles Menches also claim to have invented hamburger at a fair in Hamburg, New York, in 1885 and substituted beef for pork.
And Louis Lassen in New Haven, Connecticut is also cited as a legend for inventing the burger at his restaurant around the year of 1900.
The modern hamburger and the Hamburg steak are different as the Hamburg steak was simply just a patty and the hamburger is a patty served in a sandwich form.
