of Interferon Research (later renamed the Journal of Interferon and Cytokine Research (JICR)), he went on to serve as senior consulting editor of the JICR for ten years until the present day. For twenty-five years he was an editor for the Journal of Cellular Physiology. He typically mentored two Ph.D. candidates and two undergraduate honors students doing research in the lab. The bulk of his research at the University of Connecticut was in collaboration with long-time associate and faculty member, Dr. Margaret J. Sekellick. Three highlights included: the discovery of the world's most efficient inducer of interferon –a single molecule of double-stranded RNA; the molecular cloning of the first non-human interferon (avian); and the discovery that influenza virus populations contained previously unknown large subpopulations of noninfectious viruses that were nonetheless biologically active. He was an avid reader who, while developing ways to win the war between viruses and cells, imagined how humankind would lose if we destroyed ourselves first. He showed palatable disdain for politicians who did not appreciate the role of basic science in understanding and caring for the world and its many inhabitants. Marcus died on September 1, 2013, at the age of eighty-six. He had spent the past forty-four years on the faculty at the University of Connecticut, known to many as a compassionate professor who donated his time unselfishly to colleagues and students through his research, teaching and service. Research In 1955 he co-authored a paper on "the first practical and efficient method for growing colonies from individual animal cells", known as the clonogenic assay, which is still used today. He was also the first person to clone HeLa cells, and was editor-in-chief of the Journal of Interferon and Cytokine Research for 18 years. Marcus gives credit to Leó Szilárd for inspiring this achievement in both an interview for Genius in the Shadows, a biography of Szilárd, and in the This Week in Virology 2012 interview. Marcus' further career included positions at the Albert Einstein College of Medicine, the Cold Spring Harbor Laboratory and the Salk Institute. The primary focus of his research from 1966 until his death was in the field of interferon research. 'His Virus and Interferon Research Laboratory at UConn's Torrey Life Sciences Building became the leading proponent of the theory that double-stranded ribonucleic acid, dsRNA, is the inducer of interferon, and that just one molecule of dsRNA is enough to induce interferon
