The February 1923 issue of Popular Science
When Popular Science published its February 1923 cover story, underwater cinematography was in its infancy. Less than a decade before, film pioneer J.E. Williamson invented the first device capable of capturing footage below the surface: a steel-and-glass underwater chamber that attached to an accordionlike tube. Adding a more lifelike hue to the industry, Williamson's first aquatic color film, The Uninvited Guest, came out in 1924. Nearly 90 years later, director James Cameron worked with engineers to develop his own innovation: a submersible capable of taking IMAX-quality 3-D images at the deepest point in the ocean.
