Christopher T. Walsh (February 16, 1944 – January 10, 2023) was a Hamilton Kuhn professor of biological chemistry and pharmacology at Harvard Medical School. His research focused on enzymes and enzyme inhibition, and most recently focused on the problem of antibiotic resistance. He was elected to the National Academy of Sciences in 1989.

Education
He earned his A.B. degree in biology from Harvard University in 1965. As an undergraduate, he worked with E. O. Wilson and published a first author paper in the journal Nature, where he and his colleagues described the composition of the fire ant trail substance. He went on to graduate school at Rockefeller University, where he earned his Ph.D. in life science in 1970.

Career
Walsh completed a postdoctoral fellowship with Robert Abeles at Brandeis University in 1972, and later that year joined the faculty at Massachusetts Institute of Technology as a professor of chemistry and biology. In 1987, he joined the faculty at Harvard Medical School to serve as the chair of the newly created Department of Biological Chemistry and Molecular Pharmacology. He served as the president and CEO of the Dana–Farber Cancer Institute from 1992 to 1995. Walsh authored more than 650 publications in scholarly journals and trained several graduate students and postdoctoral researchers. Among his professional activities, Walsh was a member of the Board of Scientific Governors of The Scripps Research Institute, the American Philosophical Society, The National Academy of Sciences, Institute of Medicine, American Academy of Arts and Sciences, and the American Academy of Microbiology.

Personal life
Walsh was born in Boston and went to Roxbury Latin School. Walsh died following a fall on January 10, 2023, at the age of 78. He was married to Diana Chapman Walsh who was the president of Wellesley College from 1993 to 2007.
