Wisconsin's 6th congressional district came into existence in 1863 following the federal census of 1860. The first elected representative from the district was Walter D. McIndoe of Wausau. The district originally comprised the counties of the northern and western parts of the state. Following subsequent congressional reapportionment after each decennial census, the district's boundaries shifted eastward.
