Strutt and another spinner, Samuel Need, were introduced to Richard Arkwright who had arrived in Nottingham in about 1768, and set up his spinning frame there using horse-power to run the mill, but this was an unsatisfactory power source. In Derby, John Lombe had built a successful silk spinning mill using water power. Strutt and Need joined Arkwright in the building of a cotton mill at Cromford, using what was henceforth called Arkwright's water frame. This was the first of its kind in the world, marking the beginning of the Industrial Revolution.
