Charles Edward Chapel studied at the University of Missouri and later at the Naval Academy in Annapolis. He saw active service in Panama, Cuba, Nicaragua, Philippines, and China as a Marine Corp officer. He was discharged in 1937 after being wounded.
Chapel wrote about a variety of subjects such as aviation and forensics, as well as firearms. The exact number of articles is not known, but could be as high as several thousand, including 3,000 for Hobbies Magazine.
After his military career, he worked as an aeronautical engineer at Northrop Aeronautical Institute in California, and wrote or helped edit many of the technical manuals for the industry. He also wrote several articles on ballistics and fingerprinting for the police.
Chapel entered Republican politics in 1950, serving in the California State Assembly from 1951 until he died in office in 1967 for California's 46th District. He was a Presidential Elector in 1956.
Although he wrote articles on a variety of subjects, most of his books were about firearms, starting with Gun Collecting in 1939. His 1940 book, The Gun Collector's Handbook of Values was one of the first to provide values for non-professionals, and he contributed to later editions for many years. From the 40s until his death, he wrote at least nine books on gun topics.
His most well known book, Guns of the Old West, is considered a standard reference for Western firearms studies.
