I remember being in a little boy and spending hours staring (at least it felt like hours), mesmerized, at the little model of an old-time diver in my parents’ fish tank — I called him, Underwater-Man. The bubbles would float up, giving the illusion that there was a little man in there, exploring the seafloor. It always reminded me of the movie 20,000 Leagues Under The Sea. I always found the outfit eerie and full of mystery. According to this article from Openculture.com, the above image is the first-ever photo of a person under the sea, taken around 1899.
