The James Sansom Carpenter House was significant to Des Moines cultural history from 1906 to 1939. The 13 acre property named Oakwood estate by its owners J. S. Carpenter and his Spouse Florence L. Carpenter because of the old growth oak forestation. The Carpenters' collection was deemed by art critics as one of the finest collections of etchings and lithographs in America. The house held the Carpenter collection of 125 paintings and 350 etchings. J. S. Carpenter was also known as Sannie or Sandy after his oddly spelled middle name. J. S. Carpenter, a bridge building magnet, founded the Des Moines Association of Fine Arts in 1916. The Association members each contributed $100.00 annually for the purchase of paintings and sculptures. The members also received a 25% discount on art purchased
