Hugh Bradner who lived between (1915 – 2008) was an American physicist at the University of California who is credited with inventing the neoprene wetsuit, which helped to revolutionize scuba diving.
Life & Career
Hugh Bradner was born in Tonopah, Nevada, on November 5, 1915,but he was raised in Findlay, Ohio.His father, Donald Byal Bradner, was briefly director of the Chemical Warfare Service at Maryland's Edgewood Arsenal. His mother was Agnes Claire Bradner née Mead. He had an older brother, Mead Bradner.Bradner graduated from Ohio's Miami University in 1936 and later received his doctorate from California Institute of Technology in Pasadena, California, in 1941,writing his thesis on "Electron-optical studies of the photoelectric effect" under the supervision of William Vermillion Houston.
Wetsuit
After the war, Bradner took a position studying high-energy physics at the University of California, Berkeley under Luis Alvarez, whom he had worked with at the Manhattan Project. He remained at the University until 1961. He worked on the 1951 atomic bombing test on Enewetak Atoll in the Marshall Islands, which was part of the Operation Greenhouse nuclear test series.
Bradner's job at Berkeley required him to do a number of underwater dives. He had previously talked to United States Navy frogmen during World War II concerning the problems of staying in cold water for long periods of time, which causes the diver to lose large amounts of body heat quickly. He worked on developing a new suit that would counter this in the basement of his family's home on Scenic Avenue in Berkeley, California,and researched the new wetsuit at a conference in Coronado, California, in December 1951.According to the San Francisco Chronicle, the wetsuit was invented in 1952.Bradner and other engineers founded the Engineering Development Company (EDCO) in order to develop it.He and his colleagues tested several versions and prototypes of the wetsuit at the Scripps Institution of Oceanography in La Jolla, California. Scripps scientist and engineer Willard Bascom advised Bradner to use neoprene for the suit material, which proved successful.He found that it "would trap the water between the body and the neoprene, and the water would heat up to body temperature and keep you warm".
A 1951 letter showed that Bradner clearly understood that the insulation in such a suit was not provided by the water between the suit and the skin, but rather that this layer of water next to the skin, if trapped, would quickly heat to skin temperature, if the material in the suit were insulative. Thus, the suit only needed to limit purging by fresh cold water, and it did not need to be dry to work.He applied for a U.S. patent for the wetsuit, but his patent application was turned down due to its similar design with the flight suit. The United States Navy also did not adopt the new wetsuits because of worries that the neoprene in the wetsuits might make its swimmers easier to spot by underwater sonar and, thus, could not exclusively profit from his invention.
Bradner and his company, EDCO, tried to sell his wetsuits in the consumer market. However, he failed to successfully penetrate the wetsuit market the way others have done - including Bob Meistrell and Bill Meistrell, the founders of Body Glove, and Jack O'Neill. Various claims have been made over the years that it was the O'Neill or the Meistrell brothers who actually invented the wetsuit instead of Bradner, but recent researchers have concluded that it was Bradner who created the original wetsuit, and not his competitors. In 2005 the Los Angeles Times concluded that Bradner was the "father of the wetsuit",and a research paper published by Carolyn Rainey at the Scripps Institution of Oceanography in 1998 provided corroborating evidence.
Later Life
Bradner joined the Scripps Institute of Geophysics and Planetary Physics as a geophysicist in 1961.He became a full professor in 1963 and retired in 1980.He remained interested in oceanography, scuba diving, seashell collecting and the outdoors throughout his later years,and continued to work both on oceanographic research, as well as on the DUMAND deep ocean neutrino astronomy project, which combined his two careers in physics and oceanography.
Hugh Bradner died at the age of 92 at his home in San Diego, California, on May 5, 2008, from complications of pneumonia. He was survived by his daughter, Bari Cornet, three grandchildren and one great-granddaughter.
