Julius Hess
Julius Hess (January 26, 1876 – November 2, 1955) was an American physician who is often considered the father of American neonatology. In 1922, he published the first textbook focused on the care of prematurity and birth defects in infants. That same year, Hess and nurse Evelyn Lundeen created the first premature infant station in the United States, recognizing the importance of nursing care and temperature management in the care of preterm babies. Hess also made early contributions to the transport of such infants to specialty centers.
