HERNANDO, FL, August 24, 2023 - Leonard Gray has been included in Marquis Who's Who. As in all Marquis Who's Who biographical volumes, individuals profiled are selected on the basis of current reference value. Factors such as position, noteworthy accomplishments, visibility, and prominence in a field are all taken into account during the selection process.

Dedicating himself to the field of chemistry for over half a century, Dr. Gray initially retired from his role as the chief scientist for the U.S.-Russian Plutonium Disposition Program at the Lawrence Livermore National Laboratory in 2006. Previously, he gained valuable expertise in the nuclear weapons industry as a staff chemist with the Savannah River National Lab and Savannah River Plant. After his initial retirement Dr. Gray continued to work half-time mainly as a mentor for numerous young scientists and engineers and documenting information on the Worldwide Processing of Plutonium. He was also chairman of the "Plutonium Experts Panel" leading work in the relative new field of Plutonium Forensics to develop technical information for plutonium processing signatures for the various flow sheets used around the world.

Outside of his work, he dedicated himself to his community through the First Baptist Churches of Inverness and North Augusta and Trinity Baptist Church of Livermore, serving on the Deacon Board of Baptist Churches of North Augusta and Livermore. His service at North Augusta included two mission trips to Iringa, Tanzania. He also served one term as President of the Board of Trustees of the Trinity Baptist Church. He also served as President of the Augusta Reading Foundation, which operated a school for learning disabled children.

Dr. Gray also maintained professional alignment with the American Chemical Society and the American Nuclear Society.

Before embarking on his professional journey, Dr. Gray earned an Associate of Arts from Middle Georgia College, a Bachelor of Science in Chemistry from the New Mexico Institute of Mining and Technology, and a Master of Science in Chemistry from Texas Tech University. Subsequently, he expanded his professional knowledge, earning a PhD in Inorganic Chemistry from the University of South Carolina in 1972. Throughout his career, Dr. Gray was honored many times, including earning the Glenn T. Seaborg Actinide Separation Award in 2002.

While his career has been filled with highlights, Dr. Gray takes the most pride in the work he conducted at Lawrence Livermore National Laboratory, where he headed the chemistry section of the Laser Isotope Separations Program; and work at the Savannah River Lab where he developed processes to recover Plutonium from the scrap stockpile and reactor fuel that had been declared as non-processable. These latter two programs returned tons of plutonium from the scrap heap to the weapons foundry. This was three of the four plutonium programs that sent Russia into bankruptcy and helped to bring an end to the Cold War. The cornerstone of his success lay in growing up working with his dad, Harvey C. Gray, Sr. in the aperies of Southeast Georia which encouraged him to reach for higher goals and to never give up. Looking ahead, Dr. Gray aims to address his and his wife's current medical issues and travel more.

Dr. Gray fully retired in June 2021 and relocated to Hernando, Florida.
