Georges Hoentschel (1855–1915) was a leading French interior designer in historic styles, head of a decorating firm, and ceramicist during the Belle Epoque. He found inspiration for his designs in medieval and 18th-century French art, which he avidly collected, amassing more than 4,000 pieces of furniture, woodwork, metalwork, sculpture, paintings, and textiles. After visiting Hoentschel in Paris, the American financier J. Pierpont Morgan acquired the collection and bequeathed it to the Metropolitan Museum of Art in 1906 and 1916–17. These works greatly enriched the museum’s medieval art department and became the nucleus of its decorative arts department, profoundly influencing American tastes in the early 20th century....
