Vulcan Aircraft Co
Two brothers named Wilson and Harvey Doyle were 1925 graduates of Harvard and Yale respectively and left their home town of Charlotte, North Carolina, for Detroit, Michigan, then a center of aviation activity. After some time spent working for others and trying to obtain financial backing, they moved to Portsmouth, Ohio, where they came in contact with William Burke of the Vulcan Last Company. Burke backed their plan to build a two-place, tandem, open-cockpit parasol sportplane and the Vulcan Aircraft Division began in 1928 design work in a rented second floor room and construction in a former street car barn in Portsmouth.
The result was the Vulcan “American Moth” two-seat lightweight sporting aircraft. The plane was a hit, but the relationship among the principles was deteriorating and the Doyle brothers left to start their own Doyle Aircraft Company in Baltimore.
