Louis Ignarro was born in Brooklyn, New York. His parents were both Italian immigrants, and his father worked as a carpenter. Louis studied chemistry and pharmacology at Columbia University in New York and received his doctorate from the University of Minnesota in Minneapolis. After a period with Geigy Pharmaceuticals, in 1973 Louis Ignarro joined Tulane University in New Orleans. Since 1985 he has been associated with UCLA in Los Angeles. Louis Ignarro is married and has a daughter from a previous marriage.
Ferid Murad\'s studies of how nitroglycerin and nitric oxide (NO) cause blood vessels to expand inspired Louis Ignarro to conduct studies of his own at the end of the 1970s. He also looked for the substance that, according to Robert Furchgott, was formed in the innermost layer of blood vessels and produced a similar effect. Simultaneously with Robert Furchgott, but independently of him, Louis Ignarro revealed in 1986 that NO was this substance. The discovery has made possible new medications, such as those used to treat heart and cardiovascular diseases and impotence.
Their work and discoveries range from the formation of black holes and genetic scissors to efforts to combat hunger and develop new auction formats.
