In 1826, Thomas Jefferson requested that Simon Willard build a clock for the University of Virginia at Charlottesville. The clock was to be a turret one and would be placed into the university's rotunda. Jefferson provided all of the clock's plans and specifications. According to these plans, Willard precisely assembled all the clock's pieces.

Sometimes inventions are invented by several inventors around the same time, or may be invented in an impractical form many years before another inventor improves the invention into a more practical form. Where there is ambiguity, the date of the first known working version of the invention is used here.
The longcase clock (also known as the grandfather clock) was created to house the pendulum and works by the English clockmaker William Clement in 1670 or 1671. It was also at this time that clock cases began to be made of wood and clock faces to use enamel as well as hand-painted ceramics. In 1670, William Clement created the anchor escapement ...
There is a fusee in the earliest surviving spring-driven clock, a chamber clock made for Philip the Good in c. 1430. [109] Leonardo da Vinci , who produced the earliest known drawings of a pendulum in 1493–1494, [ 110 ] illustrated a fusee in c. 1500, a quarter of a century after the coiled spring first appeared.
It was invented by Simon Willard, originally of Grafton, Massachusetts, later of Roxbury, Massachusetts, and patented in 1802. [1] The banjo clock normally lacks a striking mechanism and indicates time only by its hands and dial, for which reason some horologists may insist upon calling it a timepiece rather than a true clock. In popular usage ...
The pendulum clock was invented on 25 December 1656 by Dutch scientist and inventor Christiaan Huygens, and patented the following year. He described it in his manuscript Horologium published in 1658. [4] Huygens contracted the construction of his clock designs to clockmaker Salomon Coster, who actually built the clock. [4]
His family later moved to Auburn, New York, where he worked as a jeweler and invented a time clock in 1888. [1] He later obtained patents of many mechanical devices. [3] Harlow E. Bundy was born in 1856 in Auburn, New York. He was a graduate of Hamilton College. He died in 1916 in Pasadena, California, after retiring from business in 1915.
