Richard Wurtman (March 9, 1936 – December 13, 2022) was an American neuroscientist who spent his career doing basic and translational neuroscience research at
Massachusetts Institute of Technology.
Early life and education
Richard Wurtman earned his undergraduate degree at
University of Pennsylvania and then went to Harvard Medical School, where he earned his MD in 1960. He did a two year residency at Massachusetts General Hospital, and then joined
Julius Axelrod's lab at the
National Institutes of Health, which was pioneering studies of neurotransmitters and the ways that drugs affect them.
Career
In 1967
Massachusetts Institute of Technology invited him to open a lab to continue the NIH work in the Department of Nutrition and Food Science, which was the only department doing ''in vivo'' work at the time. In the 1980s MIT formed a new department of Brain and Cognitive Sciences, which pulled together people working on psychology, neuroscience, and neuroscience, and Wurtman joined it.

Distinguished Professor at MIT, and by that time was also a Professor of Neuroscience in MIT’s Department of Brain & Cognitive Sciences, and a Professor of Neuropharmacology in the Harvard–MIT Division of Health Sciences & Technology.
Wurtman retired in 2011, and by that time he had published around 1,000 papers and trained around 300 students and post-docs.[

Notable findings
Much of Wurtman's work at MIT involved discovering a new function of an existing biomolecule
A biomolecule or biological molecule is a loosely used term for molecules present in organisms that are essential to one or more typically biological processes, such as cell division, morphogenesis, or development. Biomolecules include large ...
, like a hormone or neurotransmitter, figuring out how that discovery might be useful in medicine, and then trying to use that biomolecule as a drug itself, or using an existing drug to affect its function, a strategy called drug repurposing. His early affiliation with people in nutrition and food science also led him to consider ways that food and nutrient affect health.[
Wurtman was involved in the evaluations of ]aspartame

when it was first being introduced as an artificial sweetener; he initially testified on behalf of its manufacturer that it was safe, but subsequent research led him to call, in 1983, for further testing due to his concerns that consuming large amounts (not small amounts) could be harmful.
In 1994 his lab published work showing that melatonin is a hormone, secreted at night-time, needed for the induction & maintenance of normal sleep.
Along with Nicholas Zervas of Beth Israel Hospital and Harvard Medical School, another early area of Wurtman's research pertained to the neurotransmitter dopamine
Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is a neuromodulatory molecule that plays several important roles in cells. It is an organic compound, organic chemical of the catecholamine and phenethylamine families. Dopamine const ...

physiology. Wurtman's studies occurred at a time of significant growth in research and understanding of neurotransmitters, with optimistic expectations for practical outcomes.
In the 2000s his lab started exploring food components that could help maintain or improve the health of the brain, focusing on choline, uridine, and the omega-3 fatty acid DHA; this work became incorporated into the medical food product, Souvenaid.
