Dr. Marion Allen
Koerper Blumberg
07/08/1943 - 12/18/2024
Born July 8, 1943, in Washington D.C., the daughter of the late Robert Allen Koerper and Marion Rittenour Koerper. Marion passed away at home on December 18th, in San Francisco, the city she called home for 60 years.
The beloved wife of 51 years to Dr. Robert Blumberg; devoted mother of Dr. Marc Blumberg (Dr. Elizabeth Jensen-Blumberg) and Andrew Blumberg (Jessica Perez); loving grandmother of Joshua Blumberg and Tobias Blumberg; cherished sister of Jean (Robert Burke); cherished sister-in-law of Estelle Goldstein; and cherished Aunt of Emily Burke Henesey (John) and David Goldstein (Angela).
Marion received her undergraduate degree from Stanford University and her Medical Degree from the University of California School of Medicine, San Francisco (UCSF). She received her post graduate training in Pediatrics and Pediatric Hematology at University of California, San Francisco.
Retired from University of California San Francisco after a 40-year career as a Clinical Professor of Pediatrics and Pediatric Hematology. As a professor emerita of pediatric hematology at UCSF and founder of the UCSF Hemophilia Treatment Center, she helped shape the landscape of comprehensive care that we know today.
In 1978, she founded the Comprehensive Hemophilia Treatment Center at UCSF and a summer camp (Camp Hemotion) where children with bleeding disorders could enjoy an environment where medical care and childhood adventures could seamlessly coexist.
Her influence extended far beyond UCSF through her extensive collaboration with the National Hemophilia Foundation and the World Federation of Hemophilia, where she contributed to global initiatives improving care for people with bleeding disorders worldwide.
The bleeding disorders community recognized Dr. Koerper's extraordinary contributions with numerous honors, including the Lifetime Achievement Award from the National Hemophilia Foundation. During her professional career she contributed hundreds of articles on medical literature, many of which continue to influence the care of patients with bleeding disorders. A pioneering figure in hemophilia treatment, Dr. Koerper's impact on the bleeding disorders community will be felt for generations to come.
In lieu of flowers, donations in Dr. Koerper's memory may be made to the Hemophilia Foundation of Northern California (HFNC) Camp Hemotion Scholarship Fund, ensuring that her legacy of providing care and support to children with hemophilia continues for generations to come.

She was a special and inspiring woman - I loved her stories about figure skating and found her inspirational in her ability to enjoy life balancing work, family and fun. She left a mark on my heart.

I was very sad to read of Marion´s passing. I remember her first as a pediatric resident, she a young attending, in the late 1970s, a time when there were far fewer women in medicine. She was so approachable and very caring and smart. A true role model! Years later she joined our UCSF Birthmarks and Vascular Anomalies Clinic as our hematologist. We co-managed many patients and her astuteness as a clinician and scholar were very evident. My condolences to her family. May her memory be for blessing.

Marion A Koerper was my close colleague during the two decades when I served as the Director of the Blood Bank at UCSF Medical Center at Parnassus. We closely interacted in laboratory diagnosis and immune prevention of viral hepatitis and HIV/AIDS that had infected many of her hemophilia patients previously treated with cryoprecipitate. She was the most compassionate and competent pediatric hematologist who devoted her entire career to care of patients with hemophilia and their persistent infections. My condolences go out not only to her personal families but also to the families of hemophilia patients on their loss of Marion. May her soul rest in eternal peace. Om Shanti Shanti Shantihi.
