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.
