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.
Wendyâs Old Fashioned Hamburgers was founded in 1969 by Dave Thomas in Columbus, Ohio. The chain featured square hamburger patties and Frosties. In 1970, Thomas opened a second location in Columbus. This location would add the first modern drive thru window in 1971. In 1972, the first franchise is sold. By 1976, there are 500 restaurants and the company goes public. In 1978, the 1000th location opens. In 1979, Wendyâs was the first chain to introduce a salad bar.
