Dr. Marion Koerper passed away early Wednesday morning, December 18, 2024, after a courageous battle with glioblastoma. She was a professor emerita (she would be pleased that I got the Latin correct) of pediatric hematology at the University of California, San Francisco (UCSF) and the founder of the UCSF Hemophilia Treatment Center. Her father and her mother named her Marion with an “o” to help her overcome the gender barriers in medical education during an era when women were rarely admitted to medical schools.
