The most accurate experimental pendulum clock ever made [22] [23] may be the Littlemore Clock built by Edward T. Hall in the 1990s [24] (donated in 2003 to the National Watch and Clock Museum, Columbia, Pennsylvania, USA). The largest pendulum clocks, exceeding 30 m (98 ft), were built in Geneva (1972) and Gdańsk (2016). [25] [26]
In 1657 Ahasuerus's son John Fromanteel began studying pendulum clocks, invented by Christiaan Huygens (1656). [1] Before the invention of the pendulum clock, timepieces were accurate to only within ten to fifteen minutes a day.
The most accurate pendulum clocks were controlled electrically. [166] The Shortt–Synchronome clock, an electrical driven pendulum clock designed in 1921, was the first clock to be a more accurate timekeeper than the Earth itself. [167] A succession of innovations and discoveries led to the invention of the modern quartz timer.
The pendulum, due to its isochronism, could be a much better timekeeper. His son Vincenzio began building a clock, but both he and Galileo died before it was completed. The first pendulum clock was built in 1657 by Christiaan Huygens using a different design. The pendulum clock remained the world's most accurate timekeeper for 300 years, until ...

The best pendulum clocks achieved accuracy of around a second per year. [68] [69] The timekeeping accuracy of the pendulum was exceeded by the quartz crystal oscillator, invented in 1921, and quartz clocks, invented in 1927, replaced pendulum clocks as the world's best timekeepers. [2]

Invention of the pendulum clock by Christiaan Huygens by Georg Sturm (c. 1885). The motivation behind Horologium Oscillatorium (1673) goes back to the idea of using a pendulum to keep time, which had already been proposed by people engaged in astronomical observations such as Galileo. [4]
