The Hamlet Project

I wonder if there were any female tanners? And I wonder at what point jobs like that became gendered. Like, I think at one point – it was just that working people did whatever there was to do to make a living. Women farmed and sold things and probably tanned hides but it would seem by Shakespeare’s time, craftspeople were seen as male. There are no lady mechanicals, for example.
But when and how did that switch get made?
