Arizona's little-known whaling heritage includes Robert H. Paul (1830-1901), a native of Worcester, Massachusetts, who went out prospecting in the California Gold Rush, and became one of the Old West's leading peace officers.

His career intertwined with those of Wyatt Earp -- whom he tries to arrest at one point -- Curly Bob Brocius, and other Southwest notables, and he served with distinction as Sheriff of Tombstone and U.S. Marshal of the Arizona Territory in the 1880s and '90s.

His photo and a 1849-model Colt .31-calibre pocket revolver can be seen in the exhibition vignette dedicated to his memory in "Famous Whalemen: A Baker's Dozen."
