Time
The most precise timekeeping device of the ancient world was the water clock, or clepsydra, one of which was found in the tomb of Egyptian pharaoh Amenhotep I (1525–1504 BC). They could be used to measure the hours even at night, but required manual upkeep to replenish the flow of water. The Ancient Greeks and the people from Chaldea (southeastern Mesopotamia) regularly maintained timekeeping records as an essential part of their astronomical observations. Arab inventors and engineers in particular made improvements on the use of water clocks up to the Middle Ages. In the 11th century, Chinese inventors and engineers invented the first mechanical clocks driven by an escapement mechanism.
Pierre de Rivaz
Pierre de Rivaz (17111772) was a French clockmaker of the 18th century, from Saint-Gingolph. He built a clock in 1740 that was powered by variations in air temperature and pressure, a type of Atmos clock.
Astronomical clock
The first clock was built between 1352 and 1354 and stopped working sometime at the beginning of the 16th century. A second clock was then built by Herlin, Conrad Dasypodius, the Habrecht brothers, and others, between 1547 and 1574. This clock stopped working in 1788 or 1789 (as it apparently stopped working gradually, each component being disconnected
Clock Tower, Brighton
The Clock Tower (sometimes called the Jubilee Clock Tower) is a free-standing clock tower in the centre of Brighton, part of the English city of Brighton and Hove. Built in 1888 in commemoration of Queen Victoria's Golden Jubilee, the distinctive structure included innovative structural features and became a landmark in the popular and fashionable seaside resort. The city's residents "retain a nostalgic affection" for it, even though opinion is sharply divided as to the tower's architectural merit. English Heritage has listed the clock tower at Grade II for its architectural and historical importance.

Johann III Bernoulli (also known as Jean; 4 November 1744, Basel – 13 July 1807, Berlin), grandson of Johann Bernoulli, and son of Johann II Bernoulli. He was known around the world as a child prodigy. He studied at Basel and at Neuchâtel, and when thirteen years of age took the degree of doctor in philosophy. When he was fourteen, he got the degree of master of jurisprudence. At nineteen he was appointed astronomer royal of Berlin. A year later, he reorganized the astronomical observatory at the Berlin Academy. Some years after, he visited Germany, France and England, and subsequently Italy, Courland, Russia and Poland. His travel accounts were of great cultural and historical importance (1772–1776; 1777–1779; 1781). He wrote about Kashubians.
Johannes Stöffler
Johannes Stöffler was born on 10 December 1452, in Justingen near Blaubeuren on the Swabian Alb. Having received his basic education at the Blaubeuren monastery school, he registered at the newly founded University of Ingolstadt on 21 April 1472, where he was consequently promoted Baccalaureus in September 1473 and Magister in January 1476. After finishing his studies he obtained the parish of Justingen where he, besides his clerical obligations, concerned himself with astronomy, astrology and the making of astronomical instruments, clocks and celestial globes. He conducted a lively correspondence with leading humanists - for example, Johannes Reuchlin, for whom he made an Equatorium and wrote horoscopes.

Prague astronomical clock
The oldest part of the Orloj, the mechanical clock and astronomical dial, dates back to 1410 when it was made by clockmaker Mikuláš of Kadaň and Jan Šindel, then later a professor of mathematics and astronomy at Charles University. The first recorded mention of the clock was on 9 October 1410. Later, presumably around 1490, the calendar dial was added and the clock facade was decorated with gothic sculptures.
