The Immune System's Master Architect
1934 - 2009
In the intricate world of experimental immunopathology, where the body's defense systems against disease are meticulously unraveled, few names shine as brightly as that of Richard (Dick) Gregory Lynch, M.D. (1934-2009).
For nearly half a century, this passionate scientist, leader, and educator dedicated his career to understanding the delicate dance of cells and molecules that protect us from harm—and what happens when that protection goes awry.
Lynch's work laid crucial foundations for our understanding of lymphoproliferative disorders and immunodeficiency diseases, particularly multiple myeloma 1 .
Beyond his research accomplishments, Lynch served as a trusted advisor and exemplary statesman for investigative pathology, known for his integrity and humanity 1 . His story is not just one of scientific achievement, but of a life lived with purpose, curiosity, and an unwavering commitment to advancing human knowledge.
Richard Lynch's path to scientific prominence began humbly in Brooklyn, where he was born on April 9, 1934 1 .
He served as a weatherman from 1952 to 1956, participating in atomic bomb tests in the Marshall Islands at Bikini Atoll 1 .
Lynch pursued his education at the University of Missouri and The University of Rochester College of Medicine 1 .
He trained under the renowned Paul Lacy at Barnes-Jewish Hospital during his pathology residency and fellowships at Washington University in the 1960s 1 .

Clement T. and Sylvia H. Hanson Professor of Immunology and Chair of Pathology (1981-1999)
Interim Dean (1993-1994)
Lynch conducted seminal research on how the immune system controls cancers of plasma cells (plasmacytomas). His investigations revealed how these cancerous cells evade normal immune responses, opening new avenues for potential treatments 1 .
In patients with multiple myeloma, the very cancer that should stimulate immune responses instead creates a state of immunodeficiency. Lynch's work helped unravel this paradox, showing how myeloma cells disrupt normal immune function 1 .
Perhaps Lynch's most significant contribution was his research on Fc receptors—specialized proteins on immune cells that allow them to recognize and respond to antibodies. His work helped explain how these receptors regulate immune responses 1 .
Lynch summarized much of this work in his Rous-Whipple Award Lecture in 1997, which was subsequently published in The American Journal of Pathology in 1998 1 . This award was particularly meaningful to Lynch because he had once been a student fellow at The University of Rochester when Dr. George Whipple, for whom the award is partially named, was still active in the department 1 .
Lynch's approach to understanding Fc receptor biology involved a series of carefully designed experiments:
Through this systematic approach, Lynch made several key discoveries about how cancer cells interact with the immune system.
| Research Aspect | Discovery | Scientific Importance |
|---|---|---|
| Fc Receptor Expression | Cancer cells regulate Fc receptor levels | Revealed a mechanism for immune evasion |
| Immunodeficiency Link | Identified how myeloma disrupts immunity | Explained vulnerability to infections |
| Regulatory Pathways | Mapped signaling controlling Fc receptors | Suggested new therapeutic targets |
| Therapeutic Potential | Showed receptors could be manipulated | Opened doors for future treatments |
Lynch's research demonstrated that cancer cells don't just passively accept immune attacks—they actively manipulate the immune system through mechanisms like Fc receptor regulation. This represented a paradigm shift in how scientists understood cancer-immune interactions.
| Medical Field | Relevance of Fc Receptor Findings |
|---|---|
| Oncology | Understanding how cancer evades immune destruction |
| Autoimmune Disease | Insights into faulty immune regulation |
| Infectious Disease | Understanding antibody-mediated protection |
| Vaccine Development | Optimizing antibody responses |
| Therapeutic Antibodies | Improving design of antibody-based drugs |
| Research Reagent | Function in Experiments | Role in Lynch's Discoveries |
|---|---|---|
| Monoclonal Antibodies | Precisely target specific proteins | Enabled identification of cell surface markers |
| Cell Culture Media | Support growth of immune cells | Allowed long-term study of cancer cells |
| Flow Cytometry | Analyze and sort cell populations | Facilitated study of different immune cell types |
| Electron Microscopy | Visualize ultra-fine cell structures | Enabled detailed study of myeloma cells 1 |
| Radioimmunoassays | Precisely measure biological molecules | Allowed quantification of immune molecules |
| Gene Expression Tools | Study which genes are active | Helped link cellular behavior to molecular changes |
| Animal Disease Models | Study immune responses in whole organisms | Provided bridge between cells and living systems 1 |
Richard Lynch's impact extended far beyond his research laboratory. He was deeply committed to the broader scientific community and to nurturing the next generation of researchers.
Graduate Students & Postdoctoral Fellows Mentored
Journal Editorial Positions
President, American Society for Investigative Pathology
"I knew of no one else in the country who had given more time to peer review for the NIH than Dick Lynch."
As a mentor, Lynch guided nearly fifty graduate students and postdoctoral fellows throughout his career, in addition to maintaining a substantial teaching load for medical and graduate school curricula 1 . He took particular pride in mentoring Dr. Michael B. Cohen, who would eventually succeed him as Chair of Pathology at the University of Iowa 1 .
Lynch's service to the scientific community was equally impressive. He served on numerous committees, academic search committees, study sections, advisory boards, and editorial boards 1 .
His professional contributions included:
Lynch also made significant contributions to public policy, particularly in the 1990s campaign to safeguard human tissue resources for research 1 . He was an ardent spokesperson for developing consensus among patient advocates, researchers, and the US Department of Health and Human Services 1 .
Richard Gregory Lynch's life represents the very best of scientific inquiry—curiosity-driven, rigorous, and ultimately directed toward improving human health.
His nearly 50-year career spanned from the atomic testing grounds of Bikini Atoll to the most sophisticated laboratories of academic medicine, yet throughout this journey he maintained his passion for understanding the intricate workings of the immune system.
The significance of Lynch's work continues to reverberate through contemporary immunology and cancer research. His insights into Fc receptor biology provided foundational knowledge that continues to inform the development of antibody-based therapies today. His meticulous studies on plasmacytomas and multiple myeloma illuminated fundamental principles of cancer immunology that remain relevant across many forms of the disease.
Though Richard Lynch passed away on October 12, 2009, his scientific legacy lives on through the colleagues he inspired, the students he mentored, and the fundamental discoveries he contributed to our understanding of the immune system 1 . He is survived by his beloved wife Nancy, his three adult children Alison, Brendan, and Matthew, and four grandchildren 1 . His memory serves as a shining example of how one dedicated individual can illuminate the path of scientific progress for generations to follow.
