Compiling the dictionary is no easy task—especially when it’s the Oxford English Dictionary. It wasn’t just definitions that were needed, but sentences as well. A massive project ultimately passed down to editor James Murray, the project was ultimately assembled by an impressive display of 19th-century crowdsourcing. One of the most prolific contributors with tens of thousands of submissions was a man named Dr. William C. Minor. Murray struck up a friendship with the man, and eventually found he was less of a professional, practicing doctor and more of a patient at Broadmoor Criminal Lunatic Asylum, where he’d been living for decades.
