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.
In the â90s, Karcherâs partnership, CKE Restaurants, set its sights on another hamburger chain. Wilbur Hardee had opened his first restaurant in North Carolina in 1961; soon Hardeeâs became a familiar fast food sight in the Midwest and South.
