William Paul Monan (c. 1918 - 1990) was a pilot and illustrator based in the Miami area who produced a series of historical pictorial maps of locations in the Caribbean. Little is known about his early life aside from being born in New York 'about 1918'. By the mid-1940s, he had moved to Miami and begun work as a pilot with Pan American World Airways. After retiring from Pan Am, Monan served as a key 'old eagle' assisting the Federal Aviation Authority and NASA in developing aviation safety standards in the mid-1970s into the 1980s. He was instrumental in identifying safety problems, and published reports on the 'Call Sign Problem' and 'Hearback Problem,' which had led to accidents and near misses in preceding years.
