Another Lancashire inventor was Richard Arkwright, a barber, who was born at Preston, December 23, 1732, and was said to have been the youngest of thirteen children. About the year 1750 he, having married a daughter of Robert Holt, of Bolton, removed to that town, where, in 1769, he so far improved upon the invention of Lewis Paul (see p. 261) for spinning cotton by rollers, as to make it not only practicable but profitable, and thus at once opened a new era in cotton manufacture. Taking warning from the treatment which Hargreaves had received, he removed to Nottingham, where he had a small mill worked by horses, which was subsequently abandoned and a new factory built at Cromford, in Derbyshire, where the river Derwent supplied the water-power. The dispute and connection between Kay and Arkwright need not here be detailed.[231] Arkwright was also the inventor of other mechanical improvements in the manufacture of cotton. Amongst other mills built by Arkwright was one at Chorley, and this was one of those selected for destruction by the mobs in 1779, of the doings of which the _Annual Register_ for October 9 in that year records: "During the week, several mobs have assembled in different parts of the neighbourhood, and have done much mischief by destroying engines for carding and spinning cotton wool (without which the trade of this country could never be carried on to any great extent). In the neighbourhood of Chorley the mob destroyed and burned the engines and buildings erected by Mr. Arkwright at a very great expense. Two thousand or upwards attacked a large building near the same place on Sunday, from which they were repulsed, two rioters killed, and eight wounded taken prisoners. They returned strongly reinforced on Monday, and destroyed a great number of buildings, with a vast quantity of machines for spinning cotton, etc. Sir George Saville arrived (with three companies of the York Militia) whilst the buildings were in flames. The report of their intention to destroy the works in this town--Manchester--brought him here yesterday noon.
