March 1, 2019 – The National Stone, Sand and Gravel Association (NSSGA) has informed us of the passing of A. Frederick Gerstell, who died Feb. 23, at the age of 81. Gerstell contributed greatly to the aggregates industry over his career with Alpha Portland Cement Co., California Portland Cement Co. and later as chairman and CEO of CalMat and Vulcan Materials. In 1999, he served as chairman of the National Stone Association, a precursor to today’s NSSGA. I knew him to be a friendly and fair man, always willing to give of his time and talents. The entire aggregates industry mourns Fred’s passing.
