The Six Fat Dutchmen was an American polka band, formed around 1932 by Harold Loeffelmacher in New Ulm, Minnesota, United States.
The band was known mostly for playing the German-American (sometimes called "oom-pah") style of polka music that originated from Germany and the German-speaking areas of Czechoslovakia.
The band appeared often on a local television station in Mankato, Minnesota, and their popularity grew to the point where they played the Nebraska State Fair for 26 straight years.
The Six Fat Dutchmen played the Aragon and Trianon ballrooms in Chicago, broadcasting live on radio station WGN.
Singer and saxophone player Dick Dale was briefly a member of the Six Fat Dutchmen, before he became a regular on the long-running American television variety series, The Lawrence Welk Show.
