William Wrigley, Jr. was a U.S. chewing gum industrialist. He was founder and eponym of the Wm. Wrigley Jr. Company in 1891. He was born in Philadelphia, Pennsylvania.
Wrigley played an instrumental role in the development of Catalina Island, off the shore of Los Angeles, California. He bought a controlling interest in the Santa Catalina Island Company in 1919 and with the company received the island. Wrigley improved the island with public utilities, new steamships, a hotel, the Casino building, and extensive plantings of trees, shrubs, and flowers. He also sought to create an enterprise that would help employ local residents. By making use of clay and minerals found on the island at a beach near Avalon, in 1927 William Wrigley, Jr., created the Pebbly Beach quarry and tile plant. Along with creating jobs for Avalon residents, the plant also supplied material for Wrigley's numerous building projects on the island. After the building of Avalon's Casino in 1929, the Catalina Clay Products Tile and Pottery Plant began churning out handmade glazed tiles, dinnerware, and other practical household items such as bookends. Nowadays, Catalina art pottery items are highly popular antique collectibles.²
