Don Hallman, 83, of North Augusta, South Carolina, passed away on June 15, 2022, at Piedmont Hospital in Augusta, Georgia. He was admitted on May 11, and while in the hospital his doctors discovered a rare infection in his brain. The neurologists and infectious disease specialists, along with numerous ICU nurses, worked tirelessly to treat the infection but were ultimately unable to cure this difficult condition. Don passed away peacefully with his family by his side. He is survived by his loving wife of 60 years, Donna, three children and six grandchildren and two great grandchildren and his sister, Kay Strickland. Don Hallman was born on November 1, 1938 in Saluda County, South Carolina. He grew up on the family farm on what is now Hallman Road, in Ward, South Carolina, with his two sisters, Naomi and Kay, and his mother Mary and father Gordon Fhay Hallman. Throughout his childhood Don worked on the family farm picking cotton, and also worked in local peach orchards and packing sheds. The family attended Dry Creek Baptist Church, just down the road from their house, and Don will be buried at the Dry Creek cemetery beside his mother and father. He loved the area where he grew up and we are happy that he is laid to rest within sight of his family home and the church and the land he loved so well. Don was an excellent student, and after graduating from Ridge Spring High School he attended Clemson University where he earned a Bachelor of Science in Chemical Engineering in 1960. Don worked hard in school, spurred on by the motivation that he no longer wanted to pick cotton. While at Clemson, Don was in ROTC, and following his graduation he joined the Air Force and attended the Air Force Institute of Technology weather school at the University of Washington in Seattle, Washington, and earned a Certificate in Meteorology in 1961. While attending the University of Washington, Don met his wife, Donna, who grew up in Seattle and also attended and graduated from the University of Washington. After his year in Seattle, Don returned to South Carolina to his posting at Shaw Air Force base in Sumter, South Carolina, where he worked for two years as an Air Force Station Meteorologist. Following his time in the Air Force, Don continued his education at North Carolina State, joining the PhD program in Nuclear Engineering. He received his PhD in 1968 and for the rest of his life he worked in the nuclear industry. Don started his professional engineering career with DuPont at Savanah River, and after two years at Savanah River he joined a small start-up company, Radiation Technology, in Montreal, Canada. While in Canada, Don learned to speak some French, and also learned how to play darts and drink Molson Canadian beer with his Canadian friends. After three years with Radiation Technology, Don joined Babcock and Wilcox (B&W) in Lynchburg, Virginia, as a Research Scientist in their Nuclear Power Generation Division, and worked at B&W from 1972 – ¬1984. Following his many years with B&W Don returned to his beloved South Carolina, moving to North Augusta and taking a position with Georgia Power as the Superintendent of Chemistry at Plant Vogtle. After many years with Georgia Power, Don finished his career where he started, back at Savanah River working in Health Physics, where he finally retired in 2008 at the age of 70. Above all, Don was a family man and a father. He and Donna have three children, born all over the country during their professional travels. Their first son, Greg, was born at Shaw Air Force base in Sumter, South Carolina, and Don liked to brag that the total out of pocket cost of the birth of his first son was only $7 at the base hospital. Their daughter, Cindy, was born in Cary, North Carolina, while Don was in the PhD program at NC State, and their son Mark, was born in Montreal, Canada. While his children were young, Don worked tirelessly as a little league coach, coaching both little league football and little league baseball, and starting the little league football program in Montreal. When he wasn't coaching little league after work, Don loved working in his garden, and throughout his life he always kept an impressive vegetable garden. While living in Virginia, he loved vacationing at the beach on the Outer Banks of North Carolina, and his family always looked forward to the annual beach trip. When he moved back to South Carolina, Don and Donna and the extended family of children and grandchildren enjoyed many wonderful summer vacations at Harbor Island. Don loved everything about the beach vacations with his family and he especially loved the low-country boils we always cooked and enjoyed while vacationing. Don was always a sports fan, and he loved his Clemson Tigers. In his younger days he enjoyed traveling to Death Valley to watch the games in person, and in his later years he loved watching his Tigers on TV, taping the games on his VCR so he could watch them again, and again. In his retirement, Don was very active in the local MathCounts competition, raising money and helping coordinate competitions. MathCounts is a national competition for middle school students with local and state competitions. Don loved sharing his passion for mathematics and learning with this group of young students. In lieu of flowers, the family asks that donations be made to MathCounts of South Carolina to honor this passion, at https://www.mathcounts.org/about/donate-mathcounts. A celebration of Don's life will be held at 11:00 a.m., Thursday, June 23, at Dry Creek Baptist Church with the help of Mercantile Funeral Home Johnston Chapel, and the service will be officiated by Memmus Forrest and Bill Padgett. Arrangements have been entrusted to the care of Mercantile Funeral Home Johnston Chapel. Please share a memory or photo at www.edgefieldmercantilefh.com
