The mystery of why some people become sudden geniuses

Zaria Gorvett:

It was the summer of 1860 and Eadweard Muybridge was running low on books. This was somewhat problematic, since he was a bookseller. He handed his San Francisco shop over to his brother and set off on a stagecoach to buy supplies. Little did he know, he was about to change the world forever.

He was some way into his journey, in north-eastern Texas, when the coach ran into trouble. The driver cracked his whip and the horses broke into a run, leading the coach surging down a steep mountain road. Eventually it veered off and into a tree. Muybridge was catapulted into the air and cracked his head on a boulder.
