Llewellyn was born in Cardiff, Wales, United Kingdom, and graduated from Cardiff High School in 1949. He received his BSc degree in 1955 and went on to achieve his PhD degree in chemistry in 1958. He married Valerie Mya Davies-Jones, and they have three children.
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.
Llewellyn was selected as a scientist-astronaut by NASA in August 1967. He participated in flight training; however, he dropped out of flight school and resigned from NASA in September 1968.[1]
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 currently serves as Professor Emeritus in the Department of Chemical and Biomedical Engineering. His research interests include 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(IEEE Transactions on Dielectrics and Electrical Insulation 16(5): 1348-1355. Current work was presented at the 2010 American Society for Gene and Cell Therapy and he is an invited session leader at the 2010 Gordon Conference in Bioelectrochemistry.
Llewellyn's career is chronicled in the book "NASA's Scientist-Astronauts" by David Shayler and Colin Burgess.
