Chimney Sweep
This photo of unknown origin shows a chimney mater alongside a young chimney sweep. “Mary Poppins” paints a very unrealistic portrait of sweeps – in 1775, scientist Percivall Pott first published a paper linking soot to scrotal cancer, but the practice of sending small sweeps up chimneys didn’t die off for another two hundred years. Turns out sweeps aren’t as lucky as lucky can be after all.
