William Reece McWilliams, Sr. entered the Church Triumphant on April 24, 2014 after a brief illness. Affectionately known as Mac, he was born on August 21, 1918 to Shelley Neal McWilliams and Naomi Morse McWilliams, in Dalton, Georgia. Mac will be remembered by all who knew him for his keen intellect, unwavering loyalty, a kind and generous spirit, his gentle sense of humor, unassuming humility, and a constant love of God, family, and all things Georgia Tech. After graduation from Dalton High School, Mac enrolled at Georgia Tech, earning a degree in Mechanical Engineering in 1941. Mac served his country during WW II in the Army Ordinance Division in the US and Italy from 1942-1945, and achieved the rank of Major. Mac earned a second degree from Georgia Tech in its first Industrial Engineering class in 1946. In 1947, Mac began his professional career at Columbia Cooling & Heating Co., Inc., and later served as its President and CEO. In business, as in life, Mac’s credo was "Always try to do what is right." This outlook on life earned him the respect of his colleagues and peers. He was a Life member of the National Society of Professional Engineers and the American Society of Heating, Refrigerating and Air-Conditioning Engineers. Mac served as President of the Mechanical Contractors Association of South Carolina from 1975-1976 and was a longtime member of the Columbia Sertoma Club. Mac was also an ordained Elder in the Presbyterian Church USA and served as Chair of the Building Committee for Thompson Hall at Eastminster Presbyterian Church, and was also Scoutmaster for Eastminster’s Boy Scout Troop 10.

Mac is survived by his wife, Anne Kay, and three step-daughters, Cindy Ouzts (Steve), Kay Rowe (Shuford), and Sheila Arnold (John). Mac is also survived by his sons, William Reece McWilliams, Jr., M.D. (Sally), Wilson Greene McWilliams, M.D. (Katherine) and Robert Hall McWilliams (Susi), grandsons, William Reece McWilliams, III, M.D. (Lauren), Phillips Lancaster McWilliams (Christy), Andrew Legare McWilliams, James Wilson McWilliams, Peter Everett McWilliams, Robert Hall McWilliams, Jr., Larry Pedrick McWilliams, John Bennett McWilliams, and great-grandsons, William Reece McWilliams, IV and Walker Burke McWilliams. Mac was pre-deceased by his first wife, Josephine Hall Greene, to whom he was married from 1943 to 2005, two sisters, Lois McWilliams Powell and Rebecca Ruth McWilliams, and a brother, Shelley Morse McWilliams, Sr.
