"...Jack Randall...has spent more than 50 years studying and photographing tropical marine fishes...Attending UCLA after discharge from the Army in 1946, Randall dipped his long-john Army underwear in a wash basin of latex rubber cement to create possibly the first wet suit...one day at an Army-Navy surplus store, he saw a steel tank...bought it for $25, made a type of backpack and mounted the regulator on the right-hand strap at his shoulder..."
