Paul Greengard
Nobel laureate: Nobel Prize in Physiology or Medicine (2000)
Biography
Paul Greengard (December 11, 1925 – April 13, 2019) was an American neuroscientist whose groundbreaking research changed the understanding of how neurons communicate and signal in the nervous system. Born in New York City, Greengard studied at Hamilton College and earned his Ph.D. from Johns Hopkins University. He spent his career exploring the molecular workings of neurotransmitters, focusing on how chemical signals turn into cellular responses in neurons.
Greengard's key contributions included discovering how dopamine and other neurotransmitters affect neurons through protein phosphorylation. He found that many neurotransmitters work by activating enzymes that add phosphate groups to proteins, changing their activity. This discovery showed protein phosphorylation is a key part of nerve signal transmission, providing important insights into brain function and neurological disorders.
During his career, Greengard was the Vincent Astor Professor at Rockefeller University, where he did much of his Nobel Prize-winning research. His lab trained many future neuroscientists who made their own important contributions. Aside from his research, Greengard was on the Scientific Advisory Board of the Cure Alzheimer's Fund and the Scientific Council of the Brain & Behavior Research Foundation, showing his dedication to applying neuroscience research to therapies.
In 2000, Greengard won the Nobel Prize in Physiology or Medicine with Arvid Carlsson and Eric Kandel for their work on signal transmission in the nervous system. This award recognized decades of research that significantly impacted the understanding of neurological and psychiatric diseases. His findings laid the groundwork for new treatments for illnesses like Parkinson's disease, depression, and schizophrenia. Greengard was married to renowned sculptor Ursula von Rydingsvard, and their relationship was a blend of science and art. He passed away in Manhattan on April 13, 2019, leaving a scientific legacy that continues to shape neuroscience research and drug development worldwide.
Before Fame
Growing up in New York City during the Great Depression and World War II, Greengard experienced a time of rapid advances in science and a growing understanding of the brain's complexity. He got a strong liberal arts foundation from Hamilton College before moving on to graduate studies at Johns Hopkins University, a top research institution in the U.S. During the mid-20th century, neuroscience was flourishing, with new technologies and methods allowing scientists to explore the molecular workings of the brain in more detail than ever before.
Greengard entered neuroscience when the basics of synaptic transmission were being figured out, but the specific molecular details were still unclear. The discovery of neurotransmitters and new biochemical techniques for studying proteins gave young scientists the chance to uncover key insights about cellular-level brain function.
