Holmes Automobile Company, produced in the United States from 1918 to 1923, was an automobile manufacturer based in Canton, Ohio, founded by former Franklin engineer Arthur Holmes. The company specialized in premium air-cooled six-cylinder automobiles, including the Series A (1918–1919), Model I (1920), and Series 4 (1921–1923). Holmes cars gained recognition for combining the advantages of air-cooled engineering with full-size luxury bodies, positioning them above many contemporary competitors. Characterized by innovative air-cooled technology, quality construction, and limited production, Holmes remains one of the most notable independent American luxury car manufacturers of the early 1920s.
