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.
But since the local meat market was out of pork sausage, they used ground beef instead. Alas, another hamburger. The first account of serving ground meat patties on buns-taking on the look of the hamburger as we know it today-took place in 1904 at the St. Louis World Fair. But it was many years later, in 1921, that an enterprising cook from Wichita, Kansas, Walt Anderson, introduced the concept of the hamburger restaurant.
