[1] In 1882, a group of investors bought the mill and formed the Grafton Worsted Company.

Diedrich Wittenberg, the president of the group, was also the owner of the Cedarburg Woolen Company.

[2] In 1902, Wittenberg's son and his son-in-law purchased the building and formed the Badger Worsted Company, which combed, spun, dyed and packaged yarn in the building until 1980.

During the Great Depression, the company acquired the neighboring Grafton Flour Mill and converted it to worsted yarn production as well.

The building was added to the National Register of Historic Places in 1983,[3][4][5] and currently houses shops, offices, and studios.
