Rudy Rotter (1913–2001) was an American outsider and self-taught artist residing in Manitowoc, Wisconsin.
Raised in Milwaukee, he moved to Manitowoc after the War in the late 1940s to setup a dental practice.
After settling in and starting a family, he embarked on a simultaneous career as an artist.
In the following decades he produced a prodigious volume of art.
Upon retiring from dentistry in 1987, Rotter moved his artwork from the basement of his office to a large 100-year-old warehouse.
As the warehouse filled with art, it was transformed into the self-designated Rudy Rotter Museum of Sculpture.
Rotter created over 15,000 pieces of art over 45 years.
