Dr. Philip Sunshine, a Stanford University physician who helped establish neonatology as a medical specialty and revolutionized the treatment of premature infants and critically ill newborns, died on April 5 at his home in Cupertino, Calif. He was 94.
Before the 1960s, premature and critically ill newborns had very less chances of survival, and many insurance companies refused to cover their care. But Dr. Sunshine, originally a pediatric gastroenterologist, believed these fragile lives could be saved. At Stanford, he advocated for a multidisciplinary approach to treating preemies, pushing for the creation of neonatal intensive care units (NICUs) and pioneering the use of specialized formula and ventilators to support these infants.
“We were able to keep babies alive that would not have survived,” he recalled in a 2000 oral history with the American Academy of Pediatrics. “And now everybody just sort of takes this for granted.”
The early 1960s marked a turning point. In 1963, President John F. Kennedy’s son Patrick died 39 hours after being born six weeks premature, a national tragedy that brought neonatal care into the spotlight. “The Kennedy story was a big turning point,” Dr. Sunshine said in a 1998 interview with AHA News. “After that, federal research money for neonatal care became much easier to get.”
By then, Stanford had already launched one of the first neonatology departments in the country. Dr. Sunshine became its chief in 1967, leading the department until 1989. Over his long career, he trained generations of doctors who went on to serve in NICUs across the world.
When he retired in 2022, at age 92, the survival rate for babies born at 28 weeks had soared to over 90 percent — a dramatic leap from when he began his work.
“Philip is one of the ‘originals’ in neonatology, a neonatologist’s neonatologist, one of our history’s best,” wrote Dr. David K. Stevenson, his successor, in the Journal of Perinatology in 2011.
“He stands comfortably among the great leaders in neonatology and is more than simply a pioneer. He is one of the creators of our discipline.”
Dr. Sunshine recognized that caring for preemies required both technical expertise and human connection. He urged hospitals to let parents visit NICUs and hold their babies, sensing early on the benefits of skin-to-skin contact. He also championed the role of nurses, giving them more autonomy and encouraging them to voice concerns.
“Our nurses have always been very important caretakers,” he said. “Often, they would recognize problems in the baby before the physicians would. We were learning neonatology together.”
Philip Sunshine was born on June 16, 1930, in Denver, to Samuel and Mollie Sunshine, who owned a pharmacy. He earned his bachelor’s and medical degrees from the University of Colorado, completing his residency at Stanford. He later served as a lieutenant in the U.S. Navy before returning to Stanford in 1959. He trained under Louis Gluck, a pediatrician who later developed the modern neonatal intensive care unit at Yale University.
“He turned me on to caring for newborns and made everything sound so interesting,” Dr. Sunshine once said.
In many ways, his surname — Sunshine — became a symbol of the warmth and hope he brought to the most vulnerable patients and their families.
