    In 1772, Frenchmen, Sieur Freminet invented a rebreathing device that recycled the exhaled air from inside of the barrel, this was the first self-contained air device. Freminet's invention was a poor one, the inventor died from lack of oxygen after being in his own device for twenty minutes.

  • Iron Belt

    In 1825, English inventor, William James designed another self-contained breather, a cylindrical iron "belt" attached to a copper helmet. The belt held about 450 psi of air, enough for a seven-minute dive.

    Pure Oxygen Rebreather
    In 1876, Englishmen, Henry Fleuss invented a closed circuit, oxygen rebreather. His invention was originally intended to be used in the repair of an iron door of a flooded ship's chamber. Fleuss then decided to use his invention for a thirty-foot deep dive underwater. He died from the pure oxygen; oxygen is toxic to humans under pressure.

    Famous magician and escape artist, Harry Houdini (born Ehrich Weiss in Budapest, Hungary in 1874) was also an inventor. Harry Houdini astonished audiences by escaping from handcuffs, straitjackets, and locked boxes, often doing so underwater.
