A long-case floor clock, often called a grandfather clock. Before 1775 the styles of the American longcase clock closely followed those current in England. Mahogany predominated from c. 1730 to c. 1840, with walnut used earlier and up to c. 1770. Cherry and maple became increasingly popular after 1775, particularly in provincial areas. The scroll top was fashionable in the United States c. 1770, the form and ornamentation being influenced by the progression of Chippendale, Hellplewhite and Sheraton styles of furniture designs. While many native-born craftsmen developed into successful clockmakers, the majority of brass movements with dials, hands, pendulums and weights were imported from England in the period up to 1820. Most were of the eight-day type, arranged for rack striking. Brass dials decreased in popularity from c. 1780 as the imported, Birmingham-enamelled, arched 'white dial' superceded them. Often these imported dials were signed on the face by local dealers. Although case designs closely followed English styles, ornamentation with carvings and inlaid decoration was uniquely American. The 30-hour tall-clock wooden movement which developed in Connecticut achieved importance in rural communities after c. 1790 and became common by 1810. This shorter case, usually 6 ft. 6 in. High, from less expensive pine or white wood and frequently grained to simulate mahogany, was made in thousands annually by local cabinetmakers in the period 1810-20. The numerous primitive styles reflect the country furniture of New Hampshire, Pennsylvania, Ohio, etc. , where they were widely used until replaced by the Connecticut shelf clock during the early 1820s. The more sophisticated eight-day brass tall clock continued to be made in Boston, Massachusetts, and in areas of Portsmouth and Concord, New Hampshire, until c. 1840. The term 'grandfather clock' did not become general until after Henry C. Work's song 'My Grandfather's Clock', published in 1875, popularized the name.
