John Kendrew (an optician) and Thomas Porthouse (a clockmaker), both of Darlington developed the process from Richard Arkwright's water frame, and patented it in 1787. The first machine was set up in Low Mill on the River Skerne at Darlington, which Kendrew used to grind glass. They then each set up a mill of their own, Kendrew near Haughton-le-Skerne and Porthouse near Coatham Mundeville, both on the same river.
They also granted permits, enabling others to build mills, including in northeast Scotland, where early mills included those at Douglastown in Kinnettles, Bervie, Dundee. Others were built at Leeds. Matthew Murray moved from Darlington to set up a mill at Adel near Leeds, where Murray built an improved spinning machine for John Marshall. In 1791, Marshall built another mill at Holbeck in Leeds. Murray went on to became a noted textile engineer, as a partner in Fenton, Murray, and Wood.
