When you hear a chainsaw, what do you think of. A person cutting timber maybe. But have you ever given any thought to the origin of them, who came up with the idea?
Your first thought may be farther from the truth than you think. It's invention lay with in the hands of two Scottish doctors seeking to improve emergency childbirth.
In the late 18th century, two Scottish doctors, John Aitken and James Jeffray, came up with a solution for getting the job done much more quickly begore: an actual chainsaw for the groin. The world's first chainsaw was a flexible saw based on a watch chain with teeth that were moved around with a hand-crank. Now, rather than look down and see a doctor cutting away at your pelvis, you could look down and see the far more reassuring sight of a doctor furiously cranking a chainsaw like they were sharpening a pencil.
The truly horrific part of this is that somebody going to town on your nether regions with a chainsaw was actually a vast improvement. The device, finally produced in 1806, went on to be used for removing diseased joints and was eventually mechanized.
It wasn't until 1905, nearly 100 years later, that somebody thought of this horror device and decided to apply it to trees.
