The following remembrances of American Association of Cancer Research (AACR) prominent member who have recently passed in 2026 is given below. Each have contributed seminal research and discovery in the field of cancer biology and cancer risk. In many cases, their discoveries transformed the way we understand and treat cancer. A separate In Memoriam for Nobel Leaureatte Dr. J. Michael Bishop will be given in a separate post.
Joseph F. Fraumeni, Jr., MD, FAACR (04/01/1933 – 06/22/2026)
Joseph F. Fraumeni, Jr., MD, FAACR, a renowned cancer epidemiologist, a Fellow of the AACR Academy, and a former member of the AACR Board of Directors, died June 22, 2026, at the age of 93. A career researcher and leader at the National Cancer Institute, Fraumeni was a co-discoverer of the genetic condition now known as the Li-Fraumeni syndrome and launched the U.S. Atlas of Cancer Mortality, which mapped geographic variations in cancer.Born April 1, 1933, in Boston, Fraumeni earned a bachelor’s degree from Harvard College, a medical degree from Duke University School of Medicine, and a master of science in epidemiology from the Harvard University School of Public Health. He completed medical residencies at Johns Hopkins Hospital and the Memorial Sloan-Kettering Cancer Center. A member of the AACR since 1968, Fraumeni served on the AACR’s Board of Directors from 1983 to 1986. He also served the AACR as an assistant editor, senior editor, and editorial board member for Cancer Epidemiology, Biomarkers & Prevention and an assistant editor for Cancer Research. The AACR recognized him with the AACR-American Cancer Society Award for Research Excellence in Epidemiology and Prevention in 1993 and the AACR Award for Lifetime Achievement in Cancer Research in 2009. He was inducted as a member of the inaugural class of Fellows of the AACR Academy in 2013. Fraumeni was a fellow of the American College of Physicians, the American Association for the Advancement of Science, and the American Academy of Arts and Sciences, and a member of the Institute of Medicine, the Association of American Physicians, and the National Academy of Sciences.
In 1962, Fraumeni joined the Epidemiology Branch of the National Cancer Institute (NCI) as a commissioned officer in the U.S. Public Health Service (USPHS). He went on to hold several leadership positions at the NCI, including posts as head of the Ecology Studies Section, chief of the Environmental Epidemiology Branch, director of the Epidemiology and Biostatistics Program, and founding director of the Division of Cancer Epidemiology and GeneticsHe retired from the USPHS in 1999 with the rank of rear admiral and assistant surgeon general. When he retired from NCI in 2017, he was named Scientist Emeritus. He authored or co-authored more than 900 scientific publications.
His research focused the epidemiology of high cancer risk populations and, in 1969, led him to discover a familial syndrome of early-onset cancers of the breast, brain, and other malignancies known as Li-Fraumeni Syndrome. Li-Fraumeni Sydrome is characterized by inherited mutations in the p53 tumor suppressor gene.
Li-Fraumeni Syndrome
from Cleveland Clinic: Li-Fraumeni syndrome is a rare genetic disorder that increases the risk you and your family members will develop cancer. Everyone with this condition has a 90% chance of developing one or more types of cancer by age 60. About half develop cancer before they turn 40. Females with Li-Fraumeni syndrome almost always develop breast cancer.
Below is the original reference published with his colleague the late Dr, Federick Li. Thier work together over the years helped develop the discovery of cancer susceptiblitiy genes and the importance of mutations of these genes linked to increased risk of developing cancer.
Li FP, Fraumeni JF Jr. 1969. Soft-tissue sarcomas, breast cancer, and other neoplasms. A familial syndrome? Ann Intern Med 71: 747–752.
Four families were identified in which a pair of children had soft-tissue sarcomas: three sets of sibs and one set of cousins. One parent of each affected child developed cancer; carcinoma of the breast occurred in three mothers under 30 years of age. Other young adults in these families had a high frequency of cancer, with no evidence of underlying genetic disorders known to carry a high risk of neoplasia. The increased familial susceptibility to cancer was manifested not only by the large number of members affected but by a seeming excess of multiple primary neoplasms.
It wasn’t until the 1990’s that Malkin et al. that germline mutations in TP53 were associated with this disease
Malkin D, Li FP, Strong LC, Fraumeni JF Jr, Nelson CE, Kim DH, Kassel J, Gryka MA, Bischoff FZ, Tainsky MA, et al. 1990. Germ line p53 mutations in a familial syndrome of breast cancer, sarcomas, and other neoplasms. Science 250: 1233–1238.
A similar syndrome named Lynch syndrome also gave rise to early increased risk of multiple cancers but due to germline mutations in mismatch repair genes like MLH1, MSH2, MSH6, or PMS2.
Lynch HT, Mulcahy GM, Harris RE, Guirgis HA, Lynch JF. 1978. Genetic and pathologic findings in a kindred with hereditary sarcoma, breast cancer, brain tumors, leukemia, lung, laryngeal, and adrenal cortical carcinoma. Cancer 41: 2055–2064.
Pierre Chambon, MD, FAACR, a Fellow of the AACR Academy who was a pioneer in the structure and expression of genes, died May 5, 2026, at the age of 95. Chambon’s early work contributed to the discovery of PolyADPribose, the discovery of multiple RNA polymerases, major contributions to the elucidation of chromatin structure, and the discovery of animal split genes. Later work included the discovery of multiple promoter elements and their cognate factors. His research on nuclear receptors has had a marked influence on the understanding of signal transduction and endocrinology in vertebrates.
Born February 7, 1931, in Mulhouse, France, Chambon received his medical degree from the University of Strasbourg in 1958. He joined the university as a research associate, becoming an associate professor in 1962 and professor of biochemistry in 1968. He founded the Institute for Genetics and Cellular and Molecular Biology in 1994 and served as its director until 2002. He then founded the Mouse Clinical Institute and served as director until 2006. He held the chair of molecular genetics at the Collège de France from 1993 to 2003 and served as chair of molecular genetics and biology at the University of Strasbourg Institute for Advanced Study from 2012 to 2021. Chambon was elected to the French Academy of Sciences in1985, the same year in which he was elected a foreign member of both the U.S. National Academy of Sciences and the American Academy of Arts and Sciences.
Juliet M. Daniel, PhD
Juliet M. Daniel, PhD, a cell biologist who was a distinguished university professor at McMaster University in Hamilton, Ontario, and member of AACR since 2002, died April 28, 2026. She was 61 years of age. Noted for her work on genetic risk factors for breast cancer, Daniel discovered and gave the name “Kaiso” to a gene associated with triple negative breast cancer in women of African descent. Born in Barbados in 1964, Daniel obtained a bachelor’s degree in life sciences from Queen’s University in Kingston, Ontario, in 1987 and a doctorate in microbiology from University of British Columbia in Vancouver in 1993. She conducted postdoctoral research at St. Jude Children’s Research Hospital in Memphis and Vanderbilt University in Nashville. She joined McMaster as an assistant professor in 1999, the first black woman to become a member of the Faculty of Science. She was promoted to associate professor in 2005 and professor in 2012. Daniel was appointed associate dean of research and external relations for the Faculty of Science on an acting basis in 2020 and permanently in 2021. She was named strategic advisor to the university president for the Canada-Caribbean Institute (CCI) at McMaster in 2024. She was named a distinguished university professor, the highest faculty honor, in 2025. Among many other honors, she was elected a fellow of the Canadian Academy of Health Sciences in 2025, received the inaugural Canadian Cancer Society Inclusive Excellence Prize in Cancer Research in 2020, and was awarded an honorary doctorate in science by the University of the West Indies in 2021.
