Kopp's Frozen Custard is a restaurant chain located in the Milwaukee, Wisconsin area. It specializes in frozen custard and large "jumbo" hamburgers. Founded by Elsa Kopp in 1950, the restaurants continue to be heralded by local publications for their quality food. They have locations in three Milwaukee suburbs.
Kopp's was the first custard stand to offer a special "flavor of the day" in addition to the more traditional chocolate and vanilla flavors.
Elsa Kopp opened the first Kopp's stand at 6005 W. Appleton Ave., Milwaukee, Wisconsin (now the site of Junior's Frozen Custard) in 1950. A German immigrant with no prior business experience, Kopp started the stand after her husband, Karl Kopp, developed Parkinson's disease.
Some support in starting the business came from Leon Schneider, a custard machine repairman (the founder of Leon's Frozen Custard in 1942), whom Elsa Kopp had met while working at a bakery.
The Kopp's frozen custard stand rose in popularity quickly during the 1950s and was soon seen as a Milwaukee staple.
