Frances Ilg

Frances Lillian Ilg (1902– July 26, 1981) was an American pediatrician and professor at Yale University. She was an expert in infant and child development, as co-founder and director of the Gesell Institute of Child Development.

Early life and education Frances Ilg was born in Oak Park, Illinois, the daughter of Joseph Frank Ilg and Leonore Petersen Ilg. Her father worked for the railroad; her maternal grandparents were born in Norway. She graduated from Wellesley College in 1925. She trained as a physician at Cornell Medical School, earning her medical degree in 1929. She also wrote a newspaper column, "Child Behavior", which was syndicated nationally. In the 1950s and 1960s she counseled parents to "enjoy their children" and "guard their sense of fun and sense of humor"; she also advised school districts to consider emotional maturity as well as intellectual development in grade placements. "We have been over-emphasizing the gifted child," she said. In 1957 she received the William Freeman Snow Award from the American Social Hygiene Association, for "distinguished service to humanity."
