Marquis Powers Orr III January 7, 2022 Marquis Powers Orr III passed away on January 7 at age 71 at Grand Strand Medical Center. Mark was born in Pittsburgh, Pa., to the late Marquis Orr Jr. and Katherine Orr. His parents were both Pittsburgh-area natives, and he grew up in the city before moving to Maryland as an adult. He and his beloved wife, Cynthia, had two children, Elizabeth and Marquis. Mark held a bachelor’s degree in mechanical engineering and a masters of science in engineering management from Johns Hopkins University. He started his career in the steel industry before moving into nuclear power operations, and later nuclear power consulting and regulation. He retired as a senior reactor analyst at the US Department of Energy’s Nuclear Regulatory Commission. One of the professional accomplishments of which he was most proud was traveling to Japan to help secure the country’s nuclear plants after the devastating 2011 tsunami. After retiring, Mark moved to Myrtle Beach, SC, to fulfill a lifelong dream of living at the beach. He served on the board of the local homeowner’s association and was active in multiple other community and social groups. He loved dogs, the outdoors, woodworking, bicycling and swimming, and made every room he was in a little more interesting. In addition to his wife and children, he is survived by two grandchildren, Skylar and Samuel Nolan; a son-in-law, Patrick Nolan; a sister, Dr. Carolyn Orr Straw; and numerous other family and friends. A gentleman of intelligence, integrity and courage, he was loved and admired by all who knew him and will be dearly missed. In lieu of flowers, donations can be made to the Arc for people with intellectual disabilities. Private services will be held.
