|Also called: longcase clock any of various types of long-pendulum clocks in tall standing wooden cases, usually between six and eight feet tall|
tall pendulum clock enclosed in a wooden case that stands upon the floor and is typically 1.8 to 2.3 metres (6 to 7.5 feet) in height. The name grandfather clock was adopted after the song Grandfather's Clock, written in 1876 by Henry Clay Work, became popular. The first grandfather clocks featured a Classical architectural appearance, but a variety of styles have enjoyed popularity over the years. One form of early pendulum clock was wall-mounted but, because of its heavy lead weights, probably difficult to secure. It is believed that the grandfather clock was developed to support these heavier clock mechanisms
