John Fowler was an agricultural engineer and inventor who was born in Wiltshire in 1826. He worked on the mechanisation of agriculture and was based in Leeds. He is credited with the invention of steam-driven ploughing engines. He died 4 December 1864, following a hunting accident. After his death, John Fowler & Co., was then continued by Robert Fowler and Robert Eddison. In 1886 the limited company of John Fowler & Co., (Leeds) Ltd., was formed, merging with Marshall, Sons & Co., Ltd., of Gainsborough in 1947 to form Marshall-Fowler Ltd. Production finally ceased in early 1974.
