Leon Gordis

Leon Gordis (July 19, 1934 – September 7, 2015)^[1] was an American epidemiologist, professor and author, whose textbook Epidemiology provided a foundation for the understanding of epidemiologic principles and clinical applications.

The son of Fannie and Robert Gordis, Leon was born in New York City and raised in Far Rockaway, Queens. Robert was a prominent Conservative rabbi and biblical scholar at the Jewish Theological Seminary in New York. Gordis moved to Baltimore in the 1960s after earning degrees from Columbia University and the Jewish Theological Seminary,^[2] and a medical degree at the State University of New York Downstate College of Medicine. He earned a master's degree in public health (MPH) in 1966 and a doctorate of public health (DrPH) in 1968 from the Johns Hopkins School of Hygiene and Public Health (later named the Bloomberg School of Public Health). Abraham Lilienfeld, prominent public health pioneer, served as Gordis’ advisor.

Gordis completed his pediatrics training at Hopkins while also a member of the U.S. Public Health Service. He joined the faculty of the Hopkins School of Hygiene and Public Health in 1971, teaching epidemiology. Gordis then became chair of the Department of Epidemiology in 1975, a position he held until 1993.

During his tenure at Hopkins, Gordis designed and taught courses at both the School of Public Health and the Johns Hopkins School of Medicine, where he became Associate Dean for Admissions and Academic Affairs. He also authored Epidemiology, now in its fifth edition,^[3] and considered by many as the seminal textbook on epidemiologic principles and clinical practice applications. PowerPoint slides taken directly from the book have been translated for public health students around the world.

He established a cardiovascular fellowship program in 1980 with an institutional grant from the National Heart, Lung, and Blood Institute. More recently, Leon was named a visiting professor at Tel-Aviv University School of Medicine and School of Public Health in 2007.^[4] The Welch Center for Prevention, Epidemiology and Clinical Research, which has enriched the schools of public health, medicine and nursing, is in no small part a culmination of Leon’s vision and commitment to collaboration.

Gordis faced controversy from many in the health care industry in the 1990s when he served as chairman of a National Institutes of Health (NIH) expert panel, suggesting that women in their 40s may not require routine mammograms but instead, should weigh the tests' risks and benefits and decide for themselves.^[5]

Gordis died of a subdural hematoma on September 7, 2015, at Mount Sinai Roosevelt Hospital in New York. His funeral and burial were held the next day in Jerusalem. Gordis and his wife, Hadassah, were long-time residents of Pikesville, Maryland, and in later life, also lived in Israel. They have three sons, eight grandchildren, and two great-grandchildren. His son, Daniel Gordis, is an educator in Israel, serving as vice president of Shalem College.^[6]
