in 1952. She died in Cincinnati, Ohio. Real estate Crosley's primary residence was Pinecroft, an estate home built in 1929 in the Mount Airy section of Cincinnati, Ohio. He also had Seagate, a winter retreat in Manatee County, Florida, built for his first wife, Gwendolyn. In addition, Crosley owned several vacation properties. Pinecroft Pinecroft, Crosley's two-story, , Tudor Revival-style mansion and other buildings on his estate in Mount Airy was designed by New York-based architect Dwight James Baum and built in 1928–29. Crosley's daughter, Marth Page (Crosley) Kess, sold the property after her father's death in 1961, and the Franciscan Sisters of the Poor acquired the property in 1963. Saint Francis Hospital bought a portion of the property north of the Crosley mansion in 1971 and built a hospital, which was renamed Mercy Hospitals West in 2001. The land surrounding the home has been subdivided into parcels, but the Franciscan Sisters have used the mansion as a retreat since the early 1970s. Pinecroft was added to the National Register of Historic Places in 2008. Seagate Seagate, also known as the Bay Club, along Sarasota Bay in the southwest corner of Manatee County, Florida, was a Mediterranean Revival-style home designed for Crosley by New York City and Sarasota architect George Albree Freeman Jr., with Ivo A. de Minicis, a Tampa, Florida, architect, drafting the plans. Sarasota contractor Paul W. Bergman built the winter retreat in 1929–30 on a parcel of land. The two-and-a-half-story house include ten bedrooms and ten bathrooms, as well as auxiliary garages and living quarters for staff. The house contains and is reportedly the first residence built in Florida using steel-frame construction to provide protection against fires and hurricanes. After Crosley's wife, Gwendolyn, died of tuberculosis at the retreat in 1939, he rarely used the house. During World War II, Crosley allowed the U.S. Army Air Corps to use the retreat for its airmen training at the nearby Sarasota Army Air Base. Crosley sold his estate property in 1947 to the D and D Corporation. Mabel and Freeman Horton purchased the property in 1948 and owned Seagate for nearly forty years. The house and was added to the National Register of Historic Places on January 21, 1983, by a subsequent owner who intended to build an exclusive condominium project on the site using the historic house as a clubhouse, but the project failed when the economy faltered shortly
