In this episode of Lost Women of Science Conversations, Michelle Nijhuis talks to historian Catherine McNeur about how she rediscovered the lives and work of Elizabeth and Margaretta Morris, two natural scientists who made significant contributions to botany and entomology in the mid-19th Century. Elizabeth collected rare plant species and sent them to institutions around the world, and Margaretta not only discovered new insects but also helped farmers combat the pests that were devastating their fields. Nevertheless, by both design and accident, these women were lost to history. McNeur tells us how that happened and how, piece by piece, she recovered their stories.
