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.
Taco Bell was founded by Glen Bell, who first opened a hot dog stand called Bell's Drive-In in San Bernardino, California in 1946 when he was 23 years old. In 1950, he opened Bell's Hamburgers and Hot Dogs in San Bernardino's West Side barrio.
