Horace Potter learned his craft at the Cleveland School of Art, the Boston Society of Arts and crafts, his European studies in design and enameling and from colleagues like Louis Rorimer and R Guy Cowan wit whom he worked here. The generation of Frederick Miller and John Paul Miller gained expertise directly from his counsel when Frederick Miller began to work at PM in 1946. Perhaps Potter recognized the potential in Frederick Miller's talent and for carrying on the legacy of fine metal crafting when he not only hired him as principle designer, later trusting him with the store.
