Carl R. Mackerer, 76, passed peacefully on September 19, 2016.
Dr. Mackerer had a long and distinguished leadership career in medical biochemistry, toxicology, and the environmental health sciences. He received his undergraduate (1963) and graduate (1968) degrees in Biology, Chemistry, and Biochemistry from Rutgers University at Newark, New Jersey, and his doctorate in Medical Biochemistry (1972) from the University of Nebraska Medical School, Omaha, where he also served as an instructor in Biochemistry. From 1972 to 1978, he directed research in the central nervous system at Searle Laboratories, Chicago, Illinois. In 1978, he joined Mobil Oil Corporation’s newly established Environmental and Health Sciences Laboratory to manage biochemical toxicology research. He oversaw the establishment of Mobil’s Research and Testing programs and facilities in Pennington, New Jersey, and in 1989, he became General Manager of Mobil’s Environmental Health Sciences program, overseeing toxicology testing and research for the company’s more than 2,200 products, processes, and services. In 1993, Dr. Mackerer was named President of Stonybrook Laboratories, the global, wholly-owned subsidiary of Mobil Oil Corporation. After the ExxonMobil merger of 1999/2000, he formed C&C Consulting in Toxicology.
Dr. Mackerer held 17 patents for toxicology test methods and the development of non-carcinogenic or bio-resistant petroleum-based products for industrial and pharmaceutical use. He was the author of more than 200 original research publications, presentations, literature reviews, and textbook chapters. With his research team, Dr. Mackerer developed the Modified Ames Assay, in which the accurate detection of potential carcinogenic activity in heavy fuels was reduced from two years to two weeks. So effective was this test that Mobil donated the patent to the public domain for global use without restriction. Dr. Mackerer held memberships in the American Society for Pharmacology and Experimental Therapeutics, American Chemical Society, Society for Experimental Biology and Medicine, and Society of Toxicology.
Dr. Mackerer also was an avid bowling enthusiast who played competitively on national TV, and he was inducted into the Rutgers University Athletic Hall of Fame in 1984.
His spirited intelligence and quick, gentle wit will be sorely missed.
