John Curr (c. 1756 – 27 January 1823) was an English mining engineer and inventor who was the viewer of the Duke of Norfolk's collieries in Sheffield, England from 1781 to 1801.
During this time he made a number of innovations that contributed significantly to the development of the coal mining industry and railways.
[4] The career of John Curr has been subject to significant dispute, due to inaccurate statements by early authors about him and misinterpretation.
[7] Contrary to statements by his son, he was probably not there in 1774, when there were riots against the colliery lessees, who insisted on selling coal only at a yard in Sheffield.
He also referred to Mr Curr's method of 'drawing 2 corves abreast up a shaft 8½ to 9-foot diameter by means of steadying conductors'.
