R. C. Kerens, U.S. senator from Missouri and Davis's friend and fellow entrepreneur, assisted Gassaway's development by providing funds to build a Roman Catholic Church. Davis followed suit by building the Presbyterian Church, which he gave as a memorial to his wife. Davis's favorite architects, the Washington, D.C., firm of Harding and Upman, designed both. Virtually two peas in an architectural pod, they are practically identical in material, size, shape, and scale. Stylistically, the churches are close cousins as well; but, although both are Gothic, they differ in details and interior arrangements. Both are well constructed and in pristine condition.
