Grandfather clocks are freestanding, weight-driven pendulum clocks and are commonly six to eight feet tall.
Brief history and background
Also referred to as long-case clocks, floor clocks and tall-case clocks, grandfather clocks often feature intricate decoration on the hood, which frames the clock-face, or dial.
The 1876 song, “My Grandfather’s Clock”, is credited by the Oxford English Dictionary for being responsible for the term being applied to the long-case clock. Among the long-case clock classifications are ‘grandfather’, ‘grandmother’ and ‘granddaughter’ clocks. Although there is no technical distinction to specify these different terms, it is widely acknowledged that it denotes their difference in height. The majority of grandfather clocks are striking clocks, which refers to the fact that they sound the time of each hour or fraction of an hour.
During the late seventeenth century, the concept of the pendulum was structured by Dutch mathematician and horologist, Christiaan Huygens. However, English clock maker, William Clement is often credited as the creator of the grandfather clock in 1680. Clement invented the anchor escapement, a mechanism which allows a clock’s wheel to advance by each swing of a pendulum, thus making the hands of the clock to visibly move forward.
