Louis Lunch â The First Hamburger in America. I visited the birthplace of the American hamburger. Louis Lunch, open since 1895, invented the hamburger in 1900 when a patron demanded a quick lunch and Louis Lassen slapped a few steak trimmings between two slices of white bread. Thus, the hamburger was born, and very little has changed since that fateful day.
The hamburger most likely first appeared in the 19th or early 20th century. The modern hamburger was a product of the culinary needs of a society rapidly changing due to industrialization and therefore having less time to prepare and consume meals. Americans contend they were the first to combine two slices of bread and a steak of ground beef into a hamburger sandwich and sell it.
