The story follows Dr. Minor, U.S. Army (Ret.) and Dr. Murray, two men who seem at first to be extremely different, but in the end aren’t as much. Dr. Murray was a poor Scotsman who eventually ended up as the editor of the Oxford English Dictionary for many years during its development. Dr. Minor was a surgeon in the U.S. Army, and then went to England to escape what he thought were demons of the war. He shot a man dead in one of his episodes of insanity, and was sentenced to live in the Broadmoor Criminal Insane Asylum for most of the rest of his life. Dr. Murray had sent out a call for volunteers to read and write down quotes from English works to go into the dictionary, and Dr. Minor responded. He was from a rich family, and still received a paycheck from the Army, so he had been building a collection of books in his cell at the asylum. From those he submitted tens of thousands of quotes to the OED, making a huge contribution. I absolutely loved having a chance to read about the creation of the OED and the main players that made it possible. Although the book often goes into tangents that have little bearing on the main plot, this story is definitely worth reading if your are interested in language, books, or just a good history.
