In the early part of World War II, Dr. Hugh Bradner, a
University of California physicist who helped develop the
atomic bomb, talked to Navy frogmen about the problems
of being immersed in cold water for long periods of time.
“He was looking at the radical notion that you didn’t have
to stay dry to stay warm,” his daughter Bari Cornet told the
San Francisco Chronicle.
In 1951, experimenting with neoprene in the basement
of his home in Berkeley, CA, he discovered that a layer of
neoprene would trap heat between it and the body, and
the water would heat up to body temperature, keeping one
warm. Dr. Bradner, himself a diver, and a few of his colleagues
created a small company to market the “EDCO Sub-
Mariner” suit, “$45 for the short version and $75 for the full
suit,” as an ad in a 1954 edition of Skin Diver magazine put
it.
He never patented the invention and the wetsuit business
venture foundered, but plenty of people in the diving
and surfing business have made small fortunes from
Bradner’s invention. He died on May 5 at the age of 92.
