Sir Joseph Whitworth (1803-1887) is considered among the top Victorian mechanical engineers. He is best known for his development of a rationalized system of screw threads and for the screw threads that bear his name: British Standard Whitworth (BSW). He proposed this thread system in 1841 and the relevant British Standard is BS 84: 1956. His principal contribution was his introduction of new standards of accuracy in manufacturing to a degree previously unknown.
