Readers of this blog may be aware that my local maths history comes much in the form of George Green, a local miller and mathematician (indeed it is a George Green mug I am drinking from in the Math/Maths Podcast album art). I noticed the following passage in the introduction to the Proceedings of the 1990 Undergraduate Mathematics Teaching Conference written by Ken Houston:

George Green (1793-1841) who discovered “Green’s Theorem” was a miller in the village of Sneinton (now part of the City of Nottingham). Recently the windmill has been restored to working order and a visitor’s centre has been built beside it. Our conference trip was a visit to Green’s windmill and the mill centre. After our tour of the windmill and the centre there was a brisk trade in souvenir mugs and no doubt many undergraduate students of vector analysis will hear about Green’s mill next session.
