Around 1935, despite the Depression, a few breeders started to linebreed and inbreed cream-colored horses to fix their color and type. In particular, C.T. Rierson began buying cream-colored mares sired by Silver Lace and developing the American Cream breed in earnest. In 1944, a breed association, the American Cream Association, was formed by 20 owners and breeders and granted a corporate charter in the state of Iowa. In 1950, the breed was finally recognized by the Iowa Department of Agriculture, based on a 1948 recommendation by the National Stallion Enrollment Board.
