It is with great sadness that we announce the passing of Marion Cantor Cohen, PhD, at the age of 86 following a long illness.
Dr. Cohen was born in Brooklyn, New York. She earned her A.B. in Zoology from Barnard College in 1960. Following graduation, she worked as a research technician in the lab of Keffer Hartline, Nobel Laureate at Rockefeller University. After raising her three children through their early school years, she returned to academia, earning an M.A. in immunology from the State University of New York at Buffalo in 1974 and a Ph.D. in Experimental Pathology from the University of Connecticut in 1978. She subsequently held faculty appointments at the University of Connecticut, Hahnemann University, and UMDNJ-New Jersey Medical School. Even after her formal retirement, Dr. Cohen remained deeply engaged in science, reviewing journal manuscripts and grant applications, and serving on the Villanova University Institutional Review Board until her illness.
A tumor immunologist, Dr. Cohen made important contributions to understanding the interactions among cytokines, tumor cells, and the vascular endothelium. Among her many scientific accomplishments was the landmark discovery that lymphocyte derived mediators inhibit endothelial cell migration (Cohen MC et al., Science. 1982;215:301), work that helped advance understanding of communication pathways between those cell types Throughout her career, she was widely respected for her scientific rigor, intellectual curiosity, and dedication to mentorship.
Beyond her scientific achievements, Dr. Cohen was deeply committed to social justice and education. At UMDNJ-New Jersey Medical School, she established a program that introduced inner-city adolescents to careers in science and medicine, providing both educational opportunities and personal mentorship. She served as a science fair judge and organized educational programs for high school teachers. As a member of the American Society for Investigative Pathology’s Committee for Career Development, Women and Minorities, she organized workshops on professional development, including “Achieving Work-Life Balance.” She generously shared her wisdom with countless trainees and colleagues, helping many young scientists, physicians, and parents navigate the challenges of balancing career and family responsibilities.
Dr. Cohen served as captain of her college fencing team. Throughout her life, she enjoyed tennis, cooking, photography, bridge, and, in later years, canasta. She brought the same enthusiasm, creativity, and competitive spirit to her hobbies that she brought to her professional pursuits.
Dr. Cohen is survived by her husband of nearly 67 years, Stanley Cohen, MD, who was also a longtime scientific collaborator; her three children, Laurie Cohen, MD, Ronald Cohen, MD, and Kenneth Cohen, MD, and their spouses; nine grandchildren and one great-grandchild-to-be. Her legacy lives on through her family, her scientific contributions, and the many students, trainees, and colleagues whose lives she touched through her mentorship, generosity, and unwavering commitment to education and opportunity.
