Christopher T Walsh Dies At The Age of 79!
Christopher T Walsh, an internationally renowned but unconventional enzymologist, passed away on January 10 at 79 due to a fall. Walsh revolutionized the study of antibiotics, including antibiotic resistance and the natural production by living organisms of molecules that can become new medicines.
Christopher T. Walsh held the title of Emeritus Hamilton Kuhn Professor of Biological Chemistry and Molecular Pharmacology at Harvard Medical School at the time of his passing. He formerly held the positions of chair of the Department of Chemistry at MIT, founding chair of the Department of Biological Chemistry and Molecular Pharmacology (BCMP) at HMS, and president of the Dana-Farber Cancer Institute.
The work of Christopher T Walsh at MIT and HMS pioneered the interdisciplinary study of chemistry, biology, and medicine. By combining these fields, Walsh and many who came after him could advance in areas where earlier researchers had failed and provide new avenues for enhancing human health.
Uncovering the molecular mechanisms by which bacteria become resistant to medicines, particularly vancomycin, a last resort treatment for drug-resistant illnesses, was one of his key accomplishments. Walsh’s warmth, humor, support, unconventional thinking, high standards, commitment to mentoring, and gender equity impacted people just as much as his scientific accomplishments, according to those who knew him.
RIP Christopher T Walsh, a giant of chemical biology. Today @CarolynBertozzi’s Cancer Breakthroughs seminar at Stanford is dedicated to Walsh and the profound ways in which he influenced and inspired us all.

According to HMS Dean George Q. Daley, who collaborated with Walsh as faculty in BCMP, “Chris Walsh possessed a luminous intellect and a generosity of spirit that made him an inspirational leader by example: Everyone around him aspired to work harder and be more rigorous because he respected excellence and inspired excellence in others.”
According to Daley, MIT, HMS, and the HMS-affiliated Dana-Farber Cancer Institute have all benefited from his leadership. We extend our condolences for his untimely departure; our thoughts are with his family.
How Did Christopher T Walsh Begin His Professional Life?
Christopher T. Walsh was born in Boston on February 16, 1944. He described his time in High School at the challenging Roxbury Latin School in West Roxbury, Massachusetts, as a “defining experience” that fostered his love of study and confidence in his academic ability.
His research career started at Harvard College when he worked with renowned biologists E.O. Wilson and John Law to identify the pheromone found in fire ant trails. Walsh was the first author of a paper published in Nature due to his study. Walsh’s illustrious career as a researcher and author of more than 800 articles and 10 books began with this. His debut book, Enzymatic Reaction Mechanisms, was released in 1979, and his two consecutive volumes are widely regarded as classics in their respective fields.
Walsh obtained a Ph.D. in life sciences from Rockefeller University in 1965 after graduating from Harvard (known then as the Rockefeller Institute for Medical Research). He became passionate about enzymatic and natural product biosynthesis there. On a Helen Hay Whitney grant, he pursued his research on the mechanics of enzyme reactions with Robert Abeles at Brandeis University.
In 1972, MIT’s chemistry and biology departments were jointly appointed due to Walsh’s commitment to bridging the two fields. He was the chemistry department’s head during his 15 years there and oversaw a lab at the forefront of creating chemical methods to study how enzymes produce natural chemicals.
The Department of Biological Chemistry and Molecular Pharmacology, formed in 1987 through the union of the Department of Biological Chemistry and the Department of Pharmacology, hired him to serve as its chair.
He developed a top-notch interdisciplinary team of structural, chemical, and molecular biologists while serving as the chair of BCMP. By bringing in specialists in X-ray crystallography and nuclear magnetic resonance spectroscopy, he established HMS as a pioneer in structural biology, studying the molecular underpinnings of biology and illness.
David Golan, professor of BCMP at the Blavatnik Institute at HMS and dean for research operations and global programs, said of him, “He had an impeccable sense for topics that were poised to take off.” Walsh’s leadership motivated people around him to think creatively and exert more effort. He guided many trainees, especially women, over challenges brought on by a system of scientific apprenticeship that was predominately male.
Walsh also contributed to redesigning the School’s MD curriculum, known as New Pathway, and expanded the School’s possibilities for graduate study by establishing the Harvard Integrated Life Sciences program, which permits Ph.D. candidates to conduct research in many labs or departments.
According to Golan, Chris was a compassionate and generous coworker, mentor, and friend, and a giant intellectually, scientifically, and organizationally. “He changed to graduate and medical education at HMS, inspiring many of us to go beyond what we thought was possible. He will be sadly missed and cherished in our memories.
Walsh was appointed president and CEO of the Dana-Farber Cancer Institute in 1992. To focus more on research, he retired from his administrative roles at Dana-Farber and HMS in 1995. In 2010, he gave his career some thought in the Journal of Biological Chemistry.
In 2013, Walsh accepted an adjunct position at Stanford University. He was involved in the Sarafan ChEM-H cross-disciplinary initiative, which seeks to understand life at the molecular level and use that understanding to enhance human health.
According to Stanford professor Carolyn Bertozzi, whose work across chemistry and biology earned her part of the 2022 Nobel Prize in Chemistry, “Chris was naturally generous and extraordinarily wise.” He viewed his retirement as a chance to take on a new position at Stanford as a scientific mentor and advisor, supporting Chaitan Khosla and me as we designed and then created Sarafan ChEM-H from scratch. Bertozzi continued, “He was the finest biochemist of the last century, and his achievements as a scholar, teacher, mentor, and friend are simply priceless. “All who knew him to feel a deep and intense loss.”
