Wikipedia has an excellent history of the business. "The Louden Machinery Company was an American engineering, manufacturing and design company based in Fairfield, Iowa. Founded by William Louden, the company in its early years manufactured and sold the patented hay carrier that he invented in 1867. The company later expanded into a wide variety of farm equipment and, in 1906, began an Architecture Department that reportedly designed more than 25,000 barns from 1906 to 1939." Louden also had a Canadian location in Guelph, Ontario.
