Known for: In 1896 Joseph Isherwood became a surveyor for Lloyd’s Register of Shipping. As a result of his detailed examinations of ships he came up with a better way of constructing large vessels. In 1906 Joseph Isherwood patented what is known as the “Isherwood System”. This is a strong but cheap kind of construction for ships’ hulls, using longitudinal girders with fewer transverse ribs. The first ship built on these lines was the 4,000 ton S.S. “Paul Paix” built at Robert Craggs’ shipyard in Middlesbrough. By the time of his death, 2,500 ships had been built using his system. In 1933 he developed the “arcform” ship design. The first ship to use this design was the S.S.”Arcwear” of 7,000 tons. Joseph Isherwood was created a baronet in 1921 as a result of his contributions to ship design.
