William Hamilton Shortt (1881–1971) was a railway engineer and noted horologist, responsible for the design of the Shortt-Synchronome free pendulum clock, a widely used time standard, employed internationally in observatories in the period between the two World Wars.
On the left is the primary pendulum in its vacuum tank. The Shortt–Synchronome free pendulum clock is a complex precision electromechanical pendulum clock invented in 1921 by British railway engineer William Hamilton Shortt in collaboration with horologist Frank Hope-Jones, [1] and manufactured by the Synchronome Company, Ltd., of London.

A pendulum clock is a clock that uses a pendulum, ... The long narrow clocks built around these pendulums, first made by William Clement around 1680, ...
Eardley Norton, a most highly esteemed member of the Clockmakers' Company, was working between 1762 and 1794. There are clocks by him in the Royal Collection and many museums worldwide. Norton made an astronomical clock for George III which still stands in Buckingham Palace.
These were pendulum clocks which were automatically impulsed every half minute by mechanical means, the mechanism then being reset electrically. William Hamilton Shortt , a gifted railway engineer, joined the Synchronome Company in 1912 as a director, contributing towards efforts to create precision pendulum clocks.
Clocks have, over the centuries, been the high tech artifacts of their era—the water clock, the pendulum clock, Harrison’s chronometer, and so forth up to the incredible precision of atomic ...
William Frodsham (1779–1850), English clock and chronometer maker, London, chronometer. John Barwise (1780 or 1790–1842), English clock and chronometer maker. Josef Kossek (1780–1858), Czech clockmaker, Prague, precision pendulum clock.
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.
