Harold Bopp, a ceramic engineer, began working for
Rookwood Pottery in
Cincinnati,
Ohio in 1929 as the head of the chemistry and color department. Shortly after being hired, Bopp became superintendent of all Rookwood facilities. In 1939, Bopp approached the company's president John D. Wareham with ideas for helping the failing company. The
Great Depression was largely to blame for Rookwood's financial problems, but Bopp believed that selling more to wholesalers, thus reducing inventory, would increase cash flow and allow the company to make upgrades to the company's manufacturing processes. Wareham was an artist and not business-minded. He rejected Bopp's suggestions and Bopp resigned from Rookwood. He and several other former employees discussed creating a new pottery that would incorporate Bopp's ideas for the foundering Rookwood company. Bopp established the Harold F. Bopp Manufacturing Company and selected a location on
U.S. Route 25 (
Dixie Highway) in Erlanger, Kentucky. According to the trademark application, the first products intended for sale were begun on January 22, 1940. In May 1940, the first large amount of pottery was fired in the
kiln. ==Production and marketing==
