John Farey Jr.

John Farey Jr. (20 March 1791 – 17 July 1851) was an English mechanical engineer, consulting engineer and patent attorney, known for his pioneering contributions in the field of mechanical engineering. As consulting engineer Farey worked for many well-known inventors of the later Industrial Revolution, and was a witness to a number of parliamentary enquiries, inquests and court cases, and on occasion acted as an arbitrator. He was polymathic in his interests and contributed text and drawings to a number of periodicals and encyclopaedias. Farey is also remembered as the first English inventor of the ellipsograph, an instrument used by draughtsmen to inscribe ellipses.
