## History

In 1912, Iowana Dairy Farms was established by Col. G. W. French in what is today the city of Riverdale. French's herd of Holstein cattle became one of the largest and most outstanding in the United States. After the death of Col. French, Glenn Moore took over part of the operation as Iowana Milk Farm, and G. Decker French operated the other part of the operation as Iowana Holstein Farm. The Aluminum Company of America, (ALCOA), moved to the area in 1946. By the middle of 1948 the new plant's construction was finished and operations began in 1949.
