Richard, the son of a blacksmith, was adopted by the Prior of Wallingford when his father died and educated at Oxford. He then joined the monastery at St Albans and was ordained as a priest in 1317. After a further period at Oxford studying mathematics and astronomy he returned to St Albans as Abbot in 1327. Shortly after he had been elected Abbot he started work on a very elaborate astronomical clock. The escapement and the striking mechanism of this clock were unusual. The former was a variation on the verge escapement, and the hour striking (up to twenty-four) was controlled by a series of pins laid out in a helical pattern on a drum. However, timekeeping was of secondary importance as the main purpose of the clock was to show the motion of the Sun, Moon and planets (the details of the planet mechanism are lost) and to demonstrate eclipses. This was achieved in a very precise manner by a series of ingenious mechanisms, such as the elliptical wheel that was used to derive the variable motion of the sun.

Richard died of leprosy, which he had contracted during a visit to obtain papal confirmation of his appointment, and the clock was completed after his death. The last recorded reference to it was made by John Leyland, shortly before the dissolution of the monasteries. It is now known only from incomplete manuscript copies of Richard's treatise. A modern reconstruction has been made based upon J.D.North's interpretation of the manuscript.

Although known as Clement in his professional life, his baptism at Asby and his death were registered under the name of Joseph Clemmet. He worked as a slater until the age of 23, but his interest in mechanics led him to spend much of his spare time in the local blacksmith's shop. By studying books on mechanics borrowed from his cousin, a watchmaker, he taught himself and with the aid of the village blacksmith made his own lathe. By 1805 he was able to give up the slating trade and find employment as a mechanic in a small factory at Kirkby Stephen. From there he moved to Carlisle for two years, and then to Glasgow where, while working as a turner, he took lessons in drawing; he had a natural talent and soon became an expert draughtsman. From about 1809 he was employed by Leys, Mason \& Co. of Aberdeen designing and making power looms. For this work he built a screw-cutting lathe and continued his self-education. At the end of 1813, having saved about £100, he made his way to London, where he soon found employment as a mechanic and draughtsman. Within a few months he was engaged by Joseph Bramah, and after a trial period a formal agreement dated 1 April 1814 was made by which Clement was to be Chief Draughtsman and Superintendent of Bramah's Pimlico works for five years. However, Bramah died in December 1814 and after his sons took over the business it was agreed that Clement should leave before the expiry of the five-year period. He soon found employment as Chief Draughtsman with Henry Maudslay \& Co. By 1817 Clement had saved about £500, which enabled him to establish his own business at Prospect Place, Newington Butts, as a mechanical draughtsman and manufacturer of high-class machinery. For this purpose he built lathes for his own use and invented various improvements in their detailed design. In 1827 he designed and built a facing lathe which incorporated an ingenious system of infinitely variable belt gearing. He had also built his own planing machine by 1820 and another, much larger one in 1825. In 1828 Clement began making fluted taps and dies and standardized the screw threads, thus anticipating on a small scale the national standards later established by Sir Joseph Whitworth. Because of his reputation for first-class workmanship, Clement was in the 1820s engaged by Charles Babbage to carry out the construction of his first Difference Engine.
