Joseph Clement (13 June 1779 – 28 February 1844) was a British engineer and industrialist, chiefly remembered as the maker of Charles Babbage's first difference engine, between 1824 and 1833. Biography Early life Joseph Clement was born on 13 June 1779 at Great Asby in Westmorland, the son of a hand-loom weaver. Although he was taught to read and write at the local school, he learned mechanics and natural history from his father, Thomas, who had built himself a lathe. He worked, first as a weaver, then as a slater, and learned metalwork from the local blacksmith. With these skills, he built himself his own lathe, on which he turned woodwind musical instruments, which he then learned to play. By 1805 he was making looms at a factory in Kirkby Stephen, then moved first to Carlisle, then to Glasgow where he learned draughtsmanship from Peter Nicholson. By 1812 he was with Leys, Masson & Co. in Aberdeen, where he attended lectures in natural philosophy at Marischal College. Career In 1813, he moved to London, first working for Alexander Galloway in Holborn. He soon left in search of wages more suiting his skills, moving to Joseph Bramah at Pimlico. Bramah doubled the wages Galloway had paid and entered into a formal agreement with Clement for a term of five years, dated 1 April 1814, making him chief draughtsman and superintendent of Bramah's Pimlico works. Following Bramah's death, Clement took up a position as chief draughtsman at Maudslay, Sons and Field, in Lambeth, where he played a role in the design of the firm's early marine steam engines. In 1817 he left Maudslay and Field to set up his own firm, encouraged by the Duke of Northumberland, a frequent visitor to Maudslay's works. Clement had managed to save the sum of £500 and took a small workshop at 21 Prospect Place, Newington, where he set up in business as a draughtsman and manufacturer of precision machinery. In 1818 he was awarded the gold medal of the Society for the Encouragement of Arts for his invention of a machine for marking ellipses, inspired by the trammels used by carpenters. Clement's main interest was the improvement of self-acting machine tools, and especially lathes. He introduced various improvements in the construction of lathes, being awarded the gold Isis medal of the Society for the Encouragement of Arts in 1827 for his improved lathe which was
