Gregory Antone Prince (born 1948) is an American pathology researcher, businessman, author, and historian of the Latter Day Saint movement.
Prince was born and raised in Los Angeles, California. After graduating as valedictorian from Dixie College (St. George, Utah), he served a two-year mission in Brazil for The Church of Jesus Christ of Latter-day Saints (LDS Church) at age 19. Upon returning to the United States in 1969, Prince attended graduate school at the University of California, Los Angeles, receiving a D.D.S. (valedictorian) in 1973 and a Ph.D in pathology in 1975. In 1975 he and his wife, JaLynn Rasmussen, moved to Washington D.C., for a post-doctoral fellowship at the National Institutes of Health. After spending more than a decade at NIH and Johns Hopkins University, he co-founded Virion Systems, Inc. (VSI), a biotechnology company focused on the prevention and treatment of pediatric infectious diseases. Building on discoveries that Prince made as a doctoral student, VSI pioneered the prevention of respiratory syncytial virus (RSV) disease in high-risk infants through the use of monoclonal antibody. (RSV is the primary cause of infant pneumonia throughout the world.) VSI's technologies were licensed to MedImmune, Inc., and the collaborative efforts of the two companies and other partners resulted in the approval by the U.S. Food and Drug Administration of Synagis, a drug that is currently given to approximately a quarter-million high-risk infants throughout the world each year. Prince currently serves as president and CEO of VSI.
