The institution of concentrated, machine-powered, clock-disciplined production — many workers brought under one roof and synchronized to mechanical rhythms — that did not merely speed up the making of goods but reorganized human time, the laboring body, and the relationship between a worker and their work.
By the 1780s, Richard Arkwright's water-powered mill at Cromford in Derbyshire — built in 1771 — ran around the clock. Workers arrived not when their own rhythms allowed but when the mill bell rang. They left when it rang again. The machines did not wait. They had never waited for anyone. Before the factory, many domestic weavers kept more control over their daily rhythm — working by daylight, resting when the body demanded — even as merchants, deadlines, and debt pressed on them. Inside Cromford, the pace was set by water falling on a wheel. The factory was not primarily an invention for making things faster, though it did that. It was an invention for making people regular — synchronized to a machine's demand, accountable to a clock, productive on someone else's schedule. That reorganization of human time is still running.
