Molesworth's style drew from the Arts and Crafts Movement and from vernacular design characteristics of western American ranches and farms.
He worked in Chicago for a furniture company, then enlisted in the U.S. Marine Corps and served as a corporal in France in 1917, having married LaVerne that year.
Returning after the war, he worked in a bank in South Dakota, then managed the Rowe Furniture Company in Billings, Montana.
Annenberg noticed Molesworth's work in the company's storefront in Cody and gave him the commission for the new ranch.
Molesworth created 245 pieces of furniture for Ranch A, as well as lighting fixtures and accessories, choosing Navajo rugs and taxidermy to set off his designs.
