In 1949, at the height of his career, Rustin McIntosh, the director of pediatrics at Columbia University’s Babies Hospital, submitted his letter of resignation. Dr. Scott Baird, who wrote a biography on Dorothy Andersen, takes us back to this pivotal moment, which occurred at the dawn of pediatric pathology in the United States. Through archival resources, Scott explores the institutional tensions that led to this abrupt resignation. At the eye of the storm is a character we’ve come to know well, perhaps the most important person working in pediatric pathology at the time: Dr. Dorothy Andersen.
