My sister rang me from Cork last night and said did you see the neuroscientist died, the one who did all that autism research. I didn't know the name before but she said the foundation he started has helped no end of families trying to understand their children. Ar dheis Dé go raibh a anam.

Gerald David Fischbach, known to colleagues, students and friends as Gerry, was an American physician and neuroscientist who spent more than half a century studying the synapse, the junction where one nerve cell passes information to another cell or to a muscle. He pioneered the use of nerve and muscle cells grown in culture to watch synapses form, and he went on to lead some of the most important institutions in American brain science: the neurobiology department at Harvard Medical School, the National Institute of Neurological Disorders and Stroke (NINDS), Columbia University's medical center, and the Simons Foundation Autism Research Initiative (SFARI). He died peacefully at his home in Westchester County, New York, surrounded by family, on Sunday, October 25, 2026. He was 87.
Fischbach was born on November 15, 1938. The Society for Neuroscience and the Simons Foundation give his birthplace as New Rochelle, New York, while he recalled spending his first four years in Brooklyn before growing up in Mount Vernon, a suburb between the Bronx and Westchester County. His parents were children of Jewish immigrants from Russia, Romania and Austria. His father was a lawyer educated at Columbia University and Brooklyn Law School; his mother, a Hunter College graduate, was a community leader and real estate broker. He had one older sister, Joan.
He left Mount Vernon in 1956 for Colgate University on a New York State Regents Scholarship and graduated magna cum laude in 1960 with high honors in mathematics and chemistry. At Cornell University Medical College he met Ruth Zeitlin, a nursing student, in his first weeks in 1960. They married in 1962 in the house that had belonged to her parents. Bored by rote learning, he took a year off from medical school to teach himself electrophysiology in the Department of Pharmacology, an unusual choice at the time. After earning his M.D. in 1965 and an internship at the University of Washington in Seattle, he joined the Laboratory of Neurophysiology at the National Institutes of Health in 1966, a move encouraged by his cousin by marriage, the future Nobel laureate Eric Kandel.
At the NIH he showed that dissociated spinal cord and muscle cells from chick embryos would re-form working synapses in a dish, work published in Science in 1970. He later said nearly all of his subsequent ideas could be traced back to those years in Bethesda. He moved to Harvard Medical School's Department of Pharmacology in 1973, became a full professor in 1978, and in 1981 went to Washington University School of Medicine in St. Louis as Edison Professor of Neurobiology and head of the Department of Anatomy and Neurobiology. He served as president of the Society for Neuroscience in 1983 and 1984. In 1990 he returned to Harvard as Nathan Marsh Pusey Professor and chair of neurobiology at Harvard Medical School and Massachusetts General Hospital. His laboratory's long search for a nerve signal that tells muscle to build acetylcholine receptors culminated in 1993 with the purification and cloning of ARIA, a protein now recognised as a member of the neuregulin family.
In 1998 NIH director Harold Varmus recruited him to run NINDS. He reorganised the institute, championed a Parkinson's disease research plan, a White House supported conference on curing epilepsy and stroke centers, and helped create the John Porter Neuroscience Center on the NIH campus. He was put forward to succeed Varmus as NIH director, but the nomination stalled in the Senate in the final months of the Clinton administration, and he believed his outspoken support for human embryonic stem cell research may have been a factor. In 2001 he became Columbia University's executive vice president for health and biomedical sciences and dean of its faculties of health sciences and medicine, serving until 2006.
Over pastrami sandwiches at a Broadway delicatessen, Jim Simons asked him for advice on finding a director for an autism research program and ended the lunch by offering him the job. As founding director of SFARI from 2006 to 2013 he built resources such as the Simons Simplex Collection, which gathered genetic and clinical data from thousands of families, and helped grow the list of convincingly autism-linked genes from one to more than 150. He became the foundation's first chief scientist and first fellow in 2013, later served as a trustee, and an auditorium at the foundation bears his name.
He was elected to the National Academy of Sciences, the American Academy of Arts and Sciences, the Institute of Medicine (now the National Academy of Medicine) and the American Philosophical Society. He spent more than 50 summers at the Marine Biological Laboratory in Woods Hole, teaching, doing research and later serving on its board. He is survived by Ruth, his wife of 64 years, their four children, Elissa, Peter, Neal and Mark, and twelve grandchildren. A memorial service is to be held at Riverside Memorial Chapel in New York on October 30, 2026.

In their own words
“Throughout my career, I have tried to pick important questions, find important collaborators, persevere, and have fun.”
The History of Neuroscience in Autobiography, Volume 9 (Society for Neuroscience, 2016)
“I came to consider science administration, with the possibility of inspiring others, as science on a meaningful level.”
The History of Neuroscience in Autobiography, Volume 9
“It is never too late, and we must never lose hope for improvements in the quality of life for those on the autism spectrum.”
The History of Neuroscience in Autobiography, Volume 9
“Autism more and more occupied my mind because it deals with important issues in development and synapses.”
2023 interview, quoted by the Simons Foundation
“When we started this whole project, there was one convincing autism-related gene for sure, discovered in 2003. Now there are more than 150.”
Simons Foundation 25th anniversary article, 2020
“Some people say I have a 'movement' disorder, but I enjoyed every one of them and so did Ruth, my wife.”
On his many career moves, Web of Stories interview recorded July 2023
“Gerry was a visionary leader who loved hearing about new ideas and approaching difficult questions from new angles.”
Marilyn Simons, co-founder and chair of the Simons Foundation, October 2026

That foundation, SFARI, is still very active. He built it from almost nothing.
