Inner City Shepherd
This one is kind of awesome: back before the invention of a more practical solution, parks in London were maintained using a fleet of organic lawnmowers. This photo, taken in 1926, shows a shepherd with his flock on the way to a park in Kingsway. Guiding this many sheep through a bustling city was bad enough, but their droppings added yet more danger to streets that were famously overrun with manure from the many horse-drawn carriages of the era.
Scientist
This photo from 1899 shows legendary scientist Nikola Tesla conducting one of his many faraday cage experiments, observing and making notes on the flow of electricity. Somehow, despite not wearing any protective gear or even choosing to move out of the way of the path of his artificial lightning, Tesla managed to survive relatively unscathed.
