The Loch Ness Monster, 1934

If the giraffe never existed, we’d have to invent it. It’s our nature to grow bored with the improbable but real and look for the impossible. So it is with the photo of what was said to be the Loch Ness monster, purportedly taken by British doctor Robert Wilson in April 1934. Wilson, however, had simply been enlisted to cover up an earlier fraud by wild-game hunter Marmaduke Wetherell, who had been sent to Scotland by London’s Daily Mail to bag the monster. There being no monster to bag, Wetherell brought home photos of hippo prints that he said belonged to Nessie. The Mail caught wise and discredited Wetherell, who then returned to the loch with a monster made out of a toy submarine. He and his son used Wilson, a respected physician, to lend the hoax credibility. The Mail endures; Wilson’s reputation doesn’t. The Loch Ness image is something of a lodestone for conspiracy theorists and fable seekers, as is the absolutely authentic picture of the famous face on Mars taken by the Viking probe in 1976. The thrill of that find lasted only until 1998, when the Mars Global Surveyor proved the face was, as NASA said, a topographic formation, one that by that time had been nearly windblown away. We were innocents in those sweet, pre-Photoshop days. Now we know better—and we trust nothing. The art of the fake has advanced, but the charm of it, like the Martian face, is all but gone.
