Andersen Corporation was founded in 1903 as the Andersen Lumber Company by Danish immigrant Hans Jacob Andersen and his family at Hudson, Wisconsin. In 1929 the name of the firm was changed to Andersen Frame Company and in 1937 to Andersen Corporation. 
Originally Andersen Lumber Company was based in Hudson, Wisconsin where logs arrived to their location via the St. Croix River. In 1905, Andersen originated the “two bundle” method, which streamlined the window construction process. By standardizing sizes of frame pieces, then packaging them in separate horizontal and vertical pairs, units could be assembled on the job site in as little as 10 minutes. In 1908, Hans Andersen sells the lumberyards to devote all the company's efforts to the window frame business. Needing room for expansion, Andersen builds a new factory in 1913 in South Stillwater (now Bayport), Minnesota. in 1914, Fred C. Andersen becomes president. In 1916, Andersen gets back into the lumber business. In 1917, Andersen's "White Pine Frames" logo becomes its first registered trademark.
In 1923, Andersen became the first in the window industry to offer two weeks paid vacation to all 295 employees. 
In January 2, 1924, Andersen began publishing a newsletter for employees called The Frame Maker. The newsletter still exists today.
The Andersen Master Casement Window is introduced in 1932 as a completely assembled window unit—sash, frame and hardware.
Because metals are scarce during World War II, Andersen began producing the Victory Window in 1941 using parts with 97% less metal by weight and other material to support the war effort. Andersen Corporation also made wooden ammunition boxes for the war effort, which resulted in "Excellence in Production" ("E") awards  from the United States Army, United States Navy, an award that had been earned by only 5% of the more than 85,000 companies involved in producing materials for the U.S. military's war effort.  In 1941, Fred C. Andersen marries Katherine Dyer Blount and she becomes known as Kitty Andersen. In 1943, Kitty Andersen joins the Andersen Corporation Board of Directors and serves for 50 years.
In 1952, Andersen began fitting its windows with a first-of-its-kind new Welded Insulating Glass to help provide protection against condensation and frost.[ citation needed]In 1957, an Andersen Ad in the trade press is titled "A Fervent Plea for the Letter E" because journalist can't seem to get the "E" in Andersen. The Perma-Shield cladding system made its debut in 1966. The patented vinyl exterior for wood windows was developed with the help of Italian inventor Luigi Zanini. In 1978, Andersen begins its relationship with The Home Depot stores. In 1982 Andersen began advertising on national television with the slogan "Come Home to Quality, Come Home to Andersen.” In 1983, Sarah Andersen, daughter of Hugh Andersen, becomes a member of the Andersen Corporation Board of Directors. She is elected chair of the Board in 1993.
