You might not think you've seen Marmaduke Wetherell's work - he was, after all, a big game hunter early in the twentieth century. But he was responsible for this:
Wetherell had found some Nessie tracks and told the press. The National History Museum said they were a hoax, which the Daily Mail reported gleefully. Wetherell got his model-making stepson Christopher Spurling to produce something he could fool the Daily Mail with. They presented it via another friend, Robert Kenneth Wilson.
Spurling admitted the hoax in 1994. This is by no means an unknown story. I only put it up here because I had not previously registered the name Marmaduke Wetherell, and it's a good one.
