Gloria Caton received her B.S. in Chemistry (1962) from Juniata College and Ph.D. in Analytical Chemistry (1968) from Iowa State University. In her 40 years at ORNL she was involved in scientific and technical information management in the energy and environmental areas. She initiated, managed and was the webmaster for the NRC-State and Tribal Programs (STP) Website for the NRC Office of Nuclear Materials Safety and Safeguards for 16 years. This website accomplished the needs of NRC-STP to communicate quickly and accurately with the Agreement States. She also initiated websites for Industrial Materials for the Future, Continuous Fiber Ceramic Composites, and Advanced Industrial Materials. Gloria was the managing editor for the DOE Protecting Human Subjects Newsletter for 12 years and the DOE Radon Newsletter for 5 years. She also was the principal investigator for several large computer database applications on on-going energy R&D (1972-1979), acid precipitation, coal liquefaction components, etc.
She volunteers at Grace Lutheran church, Ecumenical Storehouse, and Friends of the Library.
Her hobbies include travel, photography, reading, and three grandchildren.

Lee Riedinger got his physics PhD from Vanderbilt in 1968 after spending two years working on dissertation research at Oak Ridge National Laboratory. He joined the University of Tennessee Physics faculty in 1971 and served there until his retirement in 2019. His field is experimental nuclear physics and he led many experiments at accelerators at ORNL and other labs in the U.S. and Europe. He was the UT vice chancellor for research three different times and directed the UT/ORNL Science Alliance in the 1980s. He was one of the leaders of the initiative at UT to team with Battelle and bid on the contract to manage ORNL, which succeeded as the UT-Battelle LLC tenure at ORNL began in 2000. He served on this management team from 2000 to 2006, the first four years as the deputy director for science and technology. He returned to UT in 2006 and next started the UT/ORNL Bredesen Center in 2010 and its two new interdisciplinary PhD programs, which he directed until his retirement. With co-authors Al Ekkebus, Ray Smith, and Bill Bugg, he has written a book on the long history of the partnership between UT and Oak Ridge: Critical Connections: The University of Tennessee and Oak Ridge from the Dawn of the Atomic Age to the Present, published by UT Press in 2024.

Roger Macklin
Roger was born and grew up in Oak Ridge, with its wonderful schools, cultural assets and international and science orientation. His father, Richard, had a long career at ORNL measuring neutron capture cross sections. The family lived in England 1960-61 on a scientist exchange program between ORNL and AERE Harwell. At Oak Ridge High School, Roger joined an Explorer post sponsored by ORNL Environmental Sciences Division, won the Bell Telephone Science Award, and attended a National Science Foundation summer institute in physics at Cornell U.
He attended Yale University and University of Tennessee Knoxville, earning a BA in Physics and MS in Nuclear Engineering, with the MS thesis research (neutron capture cross section measurement of U-238) done at ORNL Electron Linear Accelerator facility (ORELA). Roger completed another 2 years of graduate studies in health physics through UT evening courses at ORAU, while employed as a UT Staff Research Associate at ORELA.
Roger took a job as a Health Physicist with the Tennessee Division of Radiological Health, Knoxville office, performing radiation safety inspections/evaluations/investigations for academic, medical, and industrial users of radioactive materials and radiation machines; and incident and emergency response, including drills and FEMA-graded exercises for TVA Watts Bar and Sequoyah Nuclear Plants. He retired in 2024 as Health Physics Consultant and has been a member of the Health Physics Society (National and East TN Chapter) since the early 1990s.
Roger was an original member of Greenways Oak Ridge and has served as Vice Chair (and a Trail Steward) since mid-1990s and is also both the City of Oak Ridge Citizen Representative and Treasurer for the Great Smoky Mountains Regional Greenway Council. He served as a Court Appointed Special Advocate (for abused and neglected children) for 14 years and is returning to mediating cases with Community Mediation Services. Other organizations include ORION astronomy group, Tennessee Citizens for Wilderness Planning, and League of Women Voters. Roger has experienced 4 total solar eclipses. Other hobbies include reading, music listening, photography, and shortwave radio.
