Charles Courtney was an American locksmith, whose career spanned the early 1900's, who led a fascinating life. His skills as a locksmith (a safe technician, in particular) led him to all corners of the world; his book
Unlocking Adventure details much of it, and reads more like an adventure story than a biography. One of his adventures was opening a safe at depth. There's no pictures of the actual opening, obviously, but he does include a picture of him in his (at the time, in the 1940's) "state of the art" commercial diving suit. This was, of course, in the hard hat days... so going in now, with today's suits and gas mixes, would make for a much easier time.

The book's out of print, but highly worth the read if you can find a copy.
