Who's your favourite famous shedworker?

There's an interesting discussion on twitter at the moment in the run-up to the third National Shed Week about favourite shedworkers and garden offices. Kerri from Creative Charlie suggested artist Constantin Brancusi who worked in a small wooden shed (sadly no longer standing, although Renzo Piano reproduced Brancusi’s studio at the side of the Place Georges Pompidou, next to the Centre) in the Montparnasse quarter of Paris.

A good choice (mine was George Bernard Shaw) - but who and what are your favourites?
