LLEWELLYN, John was born on April 22, 1933 in Cardiff, United Kingdom. Son of John and Morelia (Roberts) Llewellyn.
University College, Cardiff, Wales.
After the award of his doctorate, Llewellyn moved to Ottawa, Canada and served as a post-doctoral fellow at the National Research Council. In 1960, he went to Florida State University as a research associate in the Chemistry Department and was subsequently appointed Assistant Professor. In 1964, he was jointly appointed Associate Professor in both the School of Engineering Science and the Department of Chemistry.
Having been taught to dive by aquanaut Jacques Cousteau, Llewellyn served as training director for Florida State University"s diver training program
This was one of the first scuba diving certification programs in the United States. Among those he certified was sixteen year old East. Lee Spence, who received his certification on 10 July 1964.
Spence went on to become one of the pioneers of underwater archaeology. Llewellyn"s diving gave him experience in the feeling of weightlessness, which helped prepare him for his later training as an astronaut.
Llewellyn was selected as a scientist-astronaut by National Aeronautics and Space Administration in August 1967.
He participated in flight training as part of National Aeronautics and Space Administration Astronaut Group 6. However, he dropped out of flight school and resigned from National Aeronautics and Space Administration in September 1968. While with the University of South Florida"s department of Chemical Engineering, Llewellyn also served as Director of the College of Engineering"s computing department, and later as University Director of Academic Computing, where he helped initiate USF"s programs in High-Performance Computing and electronic and distance learning.
In 2007, he retired from the directorship position and served as Professor Emeritus in the Department of Chemical and Biomedical Engineering until his death.
His research interests included the development of impedance-based sensor measurement methods and instrumentation for invivo monitoring of tissue after the application of an electric field mediated plasmid delivery protocol (Institute of Electrical and Electronics Engineers Transactions on Dielectrics and Electrical Insulation 16(5): 1348-1355. His current work was presented at the 2010 American Society for Gene and Cell Therapy and he was an invited session leader at the 2010 Gordon Conference in Bioelectrochemistry.
Llewellyn died on July 2, 2013 after suffering from a brief illness.
