Most historians agree that Gabriel Mouton, the vicar of St. Paul’s Church in Lyons, France, is the “founding father” of the metric system. He proposed a decimal system of measurement in 1670. Mouton based it on the length of one minute of arc of a great circle of the Earth (now called a nautical mile, 1852 meters). He also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). A pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. Over the years, his work was revised, improved, and extended by a number of French scientists.
