Sir Richard Arkwright (23 December 1732 – 3 August 1792) was an English inventor and a leading entrepreneur during the early Industrial Revolution. He is credited as the driving force behind the development of the spinning frame, known as the water frame after it was adapted to use water power; and he patented a rotary carding engine to convert raw cotton to 'cotton lap' prior to spinning. He was the first to develop factories housing both mechanised carding and spinning operations.
