Pediatric Surgery Pioneer Alfred de Lorimier Dies

Alfred deLorimier B&W HeadshotDr. Alfred de Lorimier, a pioneer in pediatric surgery and the founder of the Division of Pediatric Surgery at UCSF has passed away. 

The Division of Pediatric Surgery at UCSF owes much to contributions of Alfred de Lorimier. His influence has continued to shape the innovative nature of our division to this day. The Pediatric Surgery faculty and staff express our sympathy to his entire family.

Letter From the Chair of the Department of Surgery, Dr. Nancy Ascher

I am saddened to inform you of the death of our colleague Al De Lorimier.

Alfred de Lorimier attended Abraham Lincoln High School in San Francisco, attended the University of California, Berkeley for undergraduate studies where he excelled in track and field. He received his medical degree from the UCSF School of Medicine in 1956 and completed his surgical residency at UCSF during the tenure of Dr. Leon Goldman. He continued his studies in pediatric surgery at Ohio State University's Columbus Children's Hospital, and then returned to UCSF, recruited by Dr. Dunphy, to establish the specialty of pediatric surgery in Northern California.

Over the next forty years, Dr. de Lorimier built a thriving practice devoted entirely to children, working primarily at UCSF Moffitt-Long and San Francisco General Hospitals, but also covering California Pacific Medical Center and eventually Mt. Zion and Kaiser San Francisco. He founded the Division of Pediatric Surgery at UCSF and single-handedly managed a busy practice (ably assisted by his wife, Sandy). He established the Division of Pediatric Surgery and obtained funding for basic research in the physiology of diaphragmatic hernia in fetal lambs at a time when most surgeons did not pursue research.

In retirement he founded the de Lorimier Vineyard in Geyserville CA but continued to advise pediatric surgeons worldwide via a website.

His death is a loss for the UCSF community and for the entire field of pediatric surgery and pediatrics. Please join me in expressing our sympathies to his wife Sandy and his family.
