William Horne and Ernest Hemingway were lifelong friends. Horne met Hemingway while a volunteer ambulance driver for the American Red Cross during World War I. They were stationed in Schio, Italy, and drove together on the same ambulance. After Hemingway's failed engagement to Agnes von Kurowsky, they shared an apartment in Chicago during the fall of 1920. When Hemingway married Hadley Richardson in September 1921, Horne was in the wedding party. When the writer died in 1961, Horne was an honorary pallbearer.
