The story
In 1901, Arthur White incorporated White Wagon Works in Sheboygan Falls, Wisconsin, the precursor to Bemis that produced children's wooden wagons with a patented steering device. In the early 1920s, Al Bemis, with partner George Riddel, bought the majority of shares of White Wagon works and by 1928, Al Bemis took controlling interest in their shared company. In 1932, Bemis started producing toilet seats. By 1935, they started making seats for nearby Kohler Company.
