Oral History Project: Henry Metzger, MD-Interview with Henry Metzger, M.D.

Video Transcription

Video Summary

Dr. Henry Metzger, NIH scientist emeritus, recounts his life from being born in Mainz, Germany in 1932 to a long career in immunology. His family emigrated to the United States in 1938 as the Nazi threat grew; he grew up in Washington Heights, New York, learning English quickly and excelling in the city’s strong public schools. He attended the Bronx High School of Science, then went to the University of Rochester—applying to only that school—where an initially poor freshman year nearly led him to switch majors before he refocused on pre-med.<br /><br />Metzger entered Columbia medical school in the early 1950s, attracted by its academic orientation and proximity to home. He recalls rigorous training, early patient exposure, and strong immunology teaching, plus a formative first research experience. After internship and residency in internal medicine, the doctor’s draft led him to the U.S. Public Health Service at NIH, where he sought training in protein physical chemistry and began applying it to immunological problems, including autoantibodies to thyroglobulin.<br /><br />A postdoctoral period with S.J. Singer (Yale/UCSD) introduced him to conceptual, forward-looking mentorship and helped spur work on “affinity labeling” to probe antibody binding sites. Returning to NIH, he studied IgM structure and antigen binding, using paraproteins from clinical cases, and later shifted to a fundamental question—how antibodies trigger biological effects. Rejecting prevailing “allosteric change” ideas, he developed and tested models in the IgE/mast cell system, emphasizing receptor aggregation and signaling via phosphorylation.<br /><br />He praises NIH’s collaborative intramural culture and flexibility, notes science’s shift toward larger teams, and describes extensive service including leadership in the American Association of Immunologists. He reflects on mentorship, diversity challenges, and the broad societal value of scientific training, and credits a supportive spouse as essential to his career.

Henry Metzger (1932–2018) was a scientist emeritus of the Intramural Research Program of the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) at the National Institutes of Health and was formerly chief of the Section on Chemical Immunology and scientific director of the Intramural Research Program at the NIAMS. Dr. Metzger was president of The American Association of Immunologists from 1991 to 1992, secretary-treasurer from 1970 to 1986, and served on the AAI Council from 1986 to 1993. He was awarded the AAI Lifetime Achievement Award in 1999 and the AAI Distinguished Service Award in 1986.
