Patent specification drawing featuring steam engines drawn on stone by Malby & Sons. Henry Maudslay (1771-1831), English engineer, invented the first metal lathe. Following an apprenticeship with Joseph Bramah, Maudslay set up on his own in 1797 and invented several types of machinery, including a screw-cutting lathe. With Joshua Field (1757-1863) he began producing marine engines and started the firm Maudslay, Sons and Field in 1810.
