sub. Link proceeded to design a new lockout sub with a distinctive acrylic bubble as the forward pilot/observer compartment. In January 1971 the new sub was launched and commissioned to the Smithsonian Institution. It was named the Johnson Sea Link after its donors, Link and his friend John Seward Johnson I. Death of son In June 1973, Link's 31-year-old son, Edwin Clayton Link, and another diver, 51-year-old Albert D. Stover, died during a seemingly routine dive off Key West. They suffered carbon dioxide poisoning when the Johnson Sea Link became trapped in debris around a Navy destroyer, the Fred T. Berry, which had been sunk to create an artificial reef. The submersible's other two occupants survived. Over the next two years, Edwin Link designed an unmanned Cabled Observation and Rescue Device (CORD) that could free a trapped submersible. Death Edwin Link died in his sleep on September 7, 1981, in Binghamton, New York, where he had been undergoing treatment for cancer. Honors Link was awarded the Howard N. Potts Medal in 1945 for developing training devices for aviators, and the Royal Aeronautical Society Wakefield Gold Medal in 1947. He received an honorary degree from Syracuse University in 1966 and Binghamton University in 1981. In 1976, he was inducted into the National Aviation Hall of Fame. In 1992, Link was inducted into the International Air & Space Hall of Fame at the San Diego Air & Space Museum. Link donated $6 million dollars to build the engineering building on the campus of Syracuse University. The Edwin A. Link Hall of Engineering'' was dedicated in presence of Link and his family on October 16, 1970. It currently houses offices, classrooms and laboratories of the Syracuse University College of Engineering and Computer Science. From the early 1980s to the 1990s, what is now Greater Binghamton Airport was named Edwin A. Link Field-Broome County Airport his honor,. The field is still named after Link, and there is an original "Blue Box" on display in the terminal. The Link Building at Florida Institute of Technology (Melbourne, FL) is named for Edwin A. Link inventor of the Link Trainer and co-founder of the Harbor Branch Oceanographic Institution. A display of an original Link Trainer can be seen in the College of Aeronautics’ Skurla Hall, a two-minute walk from the Link Building. References Bibliography External links Biography of Edwin A.
