A native of Danzig, he studied chemistry at the University of Kiel and obtained his PhD in 1957 at the Max Planck Institute for Biochemistry in Munich, under Nobel laureate Adolf Butenandt, the discoverer of estrone and other female hormones. In the same year he moved to the Sloan Kettering Institute in New York City and almost immediately began a 40-year collaboration with the founder of this Journal, epidemiologist and cancer prevention pioneer Ernst Wynder, in a partnership that would prove to be one of the most durable and productive in cancer research. Wynder, who had already won widespread recognition

ATM/ATR inhibitor clinical trial as author of the first American study demonstrating the link between cigarette smoking and lung cancer (Wynder and Graham, 1950), understood that for all its strengths, the epidemiology of tobacco-related diseases required a strong biological

and mechanistic foundation as the basis for policy recommendations that could lead to prevention of cancer at the population level. Hoffmann provided the laboratory side of the dyad, elucidating the structure and carcinogenic potential of dozens of chemical compounds Sirolimus order isolated from tobacco smoke in an approach that combined state-of-the art analytic chemistry with in vitro experimentation and in vivo bioassays. When Wynder left Memorial Sloan-Kettering in 1969 (Sloan-Kettering had merged with Memorial Hospital in 1960) to found the American Health Foundation (AHF), (Stellman, 2006a) Hoffmann came with him and eventually became Chief of the Division of Environmental Carcinogenesis as well as Associate Director at AHF’s Naylor Dana Institute for Disease Prevention

in Valhalla, NY, until its closing in 2004. He published over 300 papers in peer-reviewed journals, including 81 co-authored ADP ribosylation factor with Wynder (Stellman, 2006b), and contributed his expertise to numerous other publications as editor or reviewer. He continued to work and publish after Wynder’s 1999 death; his most recent paper appeared in 2010 (Schwartz et al., 2010). His formidable accomplishments in the field of carcinogenesis include the discovery, with Stephen S. Hecht, of the presence and importance of an entire class of carcinogens—nitrosamines—in tobacco smoke, which they published in Science ( Hoffmann et al., 1974), and later on the identification of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) as the pre-eminent tobacco-specific nitrosamine. ( Hecht et al., 1978). He published extensively on polycyclic aromatic hydrocarbons, starting with a 1961 publication with Wynder in Nature. ( Wynder and Hoffmann, 1961). He also studied the carcinogenicity of gasoline and diesel engine exhaust and numerous other environmental pollutants. His laboratory provided many researchers with opportunities to advance their careers.
