Biography
Louis Joseph Ignarro (born May 31, 1941) is an American pharmacologist who changed the understanding of cardiovascular physiology with his research on nitric oxide. Born in Brooklyn, New York, Ignarro showed that nitric oxide is a key signaling molecule in the body, particularly in controlling blood vessel dilation and cardiovascular health. His discovery earned him the 1998 Nobel Prize in Physiology or Medicine, which he shared with Robert F. Furchgott and Ferid Murad for their work on nitric oxide in the cardiovascular system.
Ignarro's education began at Long Beach High School. He went on to study at Columbia University College of Pharmaceutical Sciences, where he got his Bachelor of Science in pharmacy in 1962. He then attended the University of Minnesota School of Medicine, earning his Ph.D. in pharmacology in 1966. After that, he received a postdoctoral fellowship in chemical pharmacology from the National Institutes of Health in 1968, which provided advanced training that shaped his career.
He held key roles at major institutions and companies. Ignarro worked as a staff scientist in the pharmaceutical division of CIBA-GEIGY Corporation in New York, gaining useful industry experience. He later spent twelve years as a pharmacology professor at Tulane University School of Medicine in New Orleans, where he did much of his foundational research on nitric oxide. In 1985, he moved to California to join the UCLA School of Medicine's department of molecular and medical pharmacology, where he was a professor until becoming professor emeritus.
In addition to the Nobel Prize, Ignarro received many other honors for his scientific contributions. In 1998, he was awarded the Basic Research Prize from the American Heart Association for his contributions to cardiovascular science. That same year, he was inducted into the National Academy of Sciences, followed by the American Academy of Sciences the next year. He also received an honorary doctorate from the Chinese University of Hong Kong. Ignarro founded the Nitric Oxide Society and is the founder and editor-in-chief of Nitric Oxide Biology and Chemistry, continuing to promote research in his field through these professional organizations.
Before Fame
Growing up in Brooklyn during the 1940s and 1950s, Ignarro experienced a time of major growth in American medicine and pharmacology. After World War II, there was a big push in medical research, with the start of the National Institutes of Health and more money going into pharmaceutical research, leading to new scientific career paths.
Ignarro's journey began with studying pharmacy at Columbia University, where he learned the basics of how drugs work and about biological systems. He chose to continue his studies in pharmacology at the University of Minnesota, diving into research on cardiovascular medicine in the 1960s. This was when scientists started to grasp the complex molecular details of heart disease and blood vessel function.
