context_page_description: A wetsuit is a garment worn to provide thermal protection while wet. It is usually made of foamed neoprene, and is worn by surfers, divers, windsurfers, canoeists, and others engaged in water sports and other activities in or on water, primarily providing thermal insulation, but also buoyancy and protection from abrasion, ultraviolet exposure and stings from marine organisms. The insulation properties of neoprene foam depend mainly on bubbles of gas enclosed within the material, which reduce its ability to conduct heat. The bubbles also give the wetsuit a low density, providing buoyancy in water.
  Hugh Bradner, a University of California, Berkeley, physicist invented the modern wetsuit in 1952. Wetsuits became available in the mid-1950s and evolved as the relatively fragile foamed neoprene was first backed, and later sandwiched, with thin sheets of tougher material such as nylon or later spandex. Improvements in the way joints in the wetsuit were made by gluing, taping and blindstitching, helped the suit to remain waterproof and reduce flushing, the replacement of water trapped between suit and body by cold water from the outside.
context_section_description: In 1952, UC Berkeley and subsequent UC San Diego SIO physicist Hugh Bradner, who is considered to be the original inventor and "father of the modern wetsuit," had the insight that a thin layer of trapped water could be tolerated between the suit fabric and the skin, so long as insulation was present in the fabric in the form of trapped bubbles. In this case, the water would quickly reach skin temperature and the air in the fabric would continue to act as the thermal insulation to keep it that way. In the popular mind, the layer of water between skin and suit has been credited with providing the insulation, but Bradner clearly understood that the suit did not need to be wet because it was not the water that provided the insulation but rather the gas in the suit fabric. He initially sent his ideas to Lauriston C. "Larry" Marshall who was involved in a U.S. Navy/National Research Council Panel on Underwater Swimmers. However, it was Willard Bascom, an engineer at the Scripps Institution of Oceanography in La Jolla, California, who suggested neoprene as a feasible material to Bradner.
  Bradner and Bascom were not overly interested in profiting from their design and were unable to successfully market a version to the public. They attempted to patent their neoprene wetsuit design, but their application was rejected because the design was viewed as too similar to a flight suit. The United States Navy also turned down Bradner's and Bascom's offer to supply its swimmers and frogmen with the new wetsuits due to concerns that the gas in the neoprene component of the suits might make it easier for naval divers to be detected by underwater sonar. The first written documentation of Bradner's invention was in a letter to Marshall, dated June 21, 1951.
  Jack O'Neill started using closed-cell neoprene foam which was shown to him by his bodysurfing friend, Harry Hind, who knew of it as an insulating material in his laboratory work. After experimenting with the material and finding it superior to other insulating foams, O'Neill founded the successful wetsuit manufacturing company called O'Neill in a San Francisco garage in 1952, later relocating to Santa Cruz, California in 1959 with the motto "It's Always Summer on the Inside". Bob and Bill Meistrell, from Manhattan Beach, California, also started experimenting with neoprene around 1953. They started a company which would later be named Body Glove.
  Neoprene was not the only material used in early wetsuits, particularly in Europe. The Pêche-Sport "isothermic" suit invented by Georges Beuchat in 1953 and the UK-made Siebe Gorman Swimsuit were both made out of sponge rubber. The Heinke Dolphin Suit of the same period, also made in England, came in a green male and a white female version, both manufactured from natural rubber lined with stockinet.
