Our associate producer, Sophie McNulty, rummages through boxes in a Connecticut basement, looking for clues to Dorothy Andersen’s life story. Pediatric critical care physician Dr. John Scott Baird, who published a biography of Dorothy Andersen in 2021, suggests we take a second look at the conventional wisdom surrounding the evolution of cystic fibrosis research in the 1950s. And in this updated episode, we interview science historian Margaret Rossiter, who coined the term “Matilda Effect” to describe how credit for work done by female scientists too often goes to their male colleagues. We examine how this affected Dorothy Andersen and her groundbreaking research into cystic fibrosis.
