The Industrial Revolution is arguably the most significant change in manufacturing history. Since it was a gradual process over almost a century, the exact start and end dates are hard to pin down. However, for me one of the key dates is the start of the first cotton mill in Britain, the Cromford Cotton Mill by Richard Arkwright. Construction of this mill started in 1771, and production began 1772, which is 250 years ago, hence time for me to write an anniversary post on the Cromford Cotton Mill.
