Who invented the clock?

In 1577, Jost Burgi invented the minute hand. Burgi's invention was part of a clock made for Tycho Brahe, an astronomer who needed an accurate clock for his stargazing.\n\nPendulum\nIn 1656, the pendulum was invented by Christian Huygens, making clocks more accurate.\n\nWrist Watch\nIn 1504, the first portable (but not very accurate) timepiece was invented in Nuremberg, Germany by Peter Henlein.The first reported person to actually wear a watch on the wrist was the French mathematician and philosopher, Blaise Pascal (1623-1662). With a piece of string, he attached his pocket watch to his wrist.\n\nQuartz\nAccording to the Smithsonian "In 1927, Canadian-born Warren Marrison, a telecommunications engineer, was searching for reliable frequency standards at Bell Telephone Laboratories. Building on earlier work in piezoelectricity, he developed a very large, highly accurate clock based on the regular vibrations of a quartz crystal in an electrical circuit" - the first quartz clock.\n\nOrigins of "Clock"\nThe word 'clock' comes from the French word "cloche" meaning bell. The Latin for bell is glocio, the Saxon is clugga and the German is glocke.\n\nStandard Time\nSir Sanford Fleming invented standard time in 1878.\nAlarm Clocks\nAn early prototype of the alarm clock was invented by the Greeks around 250 BC. The Greeks built a water clock where the raising waters would both keep time and eventually hit a mechanical bird that triggered an alarming whistle.\n\nThe first mechanical alarm clock was invented by Levi Hutchins of Concord, New Hampshire, in 1787. However, the ringing bell alarm on his clock could ring only at 4 am. On October 24, 1876 a mechanical wind-up alarm clock that could be set for any time was patented (#183,725) by Seth E Thomas.\n\nSelf-winding Watch\nSwiss John Harwood invented the self-winding watch in 1923.\n\nClock Companies\nIn 1908, the Westclox Clock Company is issued a patent for the Big Ben alarm clock. The outstanding feature on this clock is the bell-back, which completely envelops the inner case back and is an integral part of the case. The bell-back provides a loud alarm.\n\nThe Warren Clock Company was formed in 1912 by Mr. Henry Warren as President. The company started by producing a new type of clock run by batteries, prior to that, clocks were either wound or run by weights.

I don't know that the burglar alarm can be attributed to any single inventor.  ADT is the oldest alarm company in the United States.  Their web site includes a history of the company back to the 1800s.\n\nhttp://www.adt.com/adt/about_adt/company_history/

The first reasonably accurate mechanical clocks measured time with weighted pendulums, which are useless at sea or in watches. The invention of a spring mechanism was crucial for portable clocks. In Tudor England, the development of "pocket-clockes" was enabled through the development of reliable springs and escapement mechanisms, which allowed clockmakers to compress a timekeeping device into a small, portable compartment. In 1524, Peter Henlein created the first pocket watch. It is rumoured that Henry VIII (the portrait of Henry VIII at this link shows the medallion thought to be the back of his watch) had a pocket clock which he kept on a chain around his neck. However, these watches only had an hour hand - a minute hand would have been useless considering the inaccuracy of the watch mechanism. Eventually, miniaturization of these spring-based designs allowed for accurate portable timepieces which worked well even at sea. Aaron Lufkin Dennison founded Waltham Watch Company in 1850, which was the pioneer of the industrial manufacturing by interchangeable parts, the American System of Watch Manufacturing.

hello.obviously the answer from any keyboard would be albert einstein.we hav many instances to name as why he is prodigious in math and physical calclations...

A technological development that permitted sailors to estimate how far east and west they are is the invention of portable, reliable timepieces.  There is a wonderful non-fiction book about this called "Longitude" by Dave Sobel.\n\nhttp://www.amazon.com/Longitude-Genius-Greatest-Scientific-Problem/dp/0140258795/\n\nThe concept of time based navigation had been around for quite a while, but it took a long concerted effort to develop the tools necessary. John Harrison developed his first mechanical chronometer over seven years and tested it at sea for the first time in 1738.\n\nAs was said above, North-South navigation has been around since prehistory.

Time to get a new clock.

The o means "of".  Therefore "o'clock" means "of the clock".

Hmmm.. People have been measuring time since antiquity. At first they used the position of the sun in the sky (or the stars at night) and the variations due to the seasons. Water clocks were often used in antiquity also, but they were not very accurate.\n\nMechanical clocks of reasonable accuracy became possible after 1200 with the invention of what is called the 'escapement mechanism', but at that time an accuracy of within an hour over a month was good.\n\nGalileo used a pendulum to control the accuracy of clocks about 1600 and this, with the escapement mechanism lead to a greatly improved accuracy then. Several modifications were made for the next century or so and by the middle 1700s the accuracy was within one second over a few months. This lead to the solution of the 'longitude problem'.

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who developed many devices which greatly influenced life in the 20th century. Dubbed "The Wizard of Menlo Park" by a newspaper reporter, he was one of the first inventors to apply the principles of mass production to the process of invention, and can therefore be credited with the creation of the first industrial research laboratory. Some of the inventions credited to him were not completely original, but alterations of earlier patents (most famously the light bulb), or were actually the work of his numerous employees. Nevertheless, Edison is considered one of the most prolific inventors in history, holding 1,097 U.S. patents in his name, as well as many patents in the United Kingdom, France, and Germany.

mankind didn't "invent" the system of time, but just rather makes use of it. time is something that we "notice" as the laws of thermodynamics occur in the universe. everything is cooling down and so time progresses... sort of. thats another subject (time doesnt really exist)...\n"standard time" on the other hand is something that we began to use to - believe it or not - to keep up with train schedules. it is merely standardized for many regions to use and not confuse anyone. first thought of by Dr. William Wollaston (1766-1828) is was adopted by the The Great Western Railway in November 1840 - GMT London time was born! standard time was instituted in the US by the railroads on Nov. 18, 1883 (about the same time as the electric safety elevator)\nthe idea of daylight savings time - used to make better use of the daylight - was conceived by Benjamin Franklin while he was in Paris in 1784. \nUTC is Coordinated Universal Time and helps keep everyone on schedule.\nas for waaaaay back in history, we just kept noticing people getting older and dying and stories getting handed down the line. many different calendars were made by the watching stars farther back than most "written" records go, but the modern calendar is gregorian and centers around the birth of Christ - but is about 4 to 6 years off (on the late end).
