Another factor that contributed to the development of modern neonatology was Dr. Martin Couney and his permanent installment of premature babies in incubators at Coney Island. A more controversial figure, he studied under Dr. Budin and brought attention to premature babies and their plight through his display of infants as sideshow attractions at Coney Island and the World's Fair in New York and Chicago in 1933 and 1939, respectively. Infants had also previously been displayed in incubators at the 1897, 1898, 1901, and 1904 World Fairs.
