Delbert Arthur Fisher

August 12, 1928 to March 4, 2026

Dr. Delbert Arthur Fisher, a devoted husband, father, grandfather, colleague and friend, passed away peacefully at his home in Solana Beach, California at the age of 97. He was born on August 12, 1928, in Diamond Springs, California.

Del attended the University of California, Berkeley, where he met his beloved wife, Beverly, during their senior year. They graduated together in 1950 and married on January 28, 1951, in Jackson, California. The couple moved to San Francisco, where Del pursued his medical education at UCSF School of Medicine, earning his Doctor of Medicine degree.

In 1955, Del's service to his country began when he was drafted as a Medical Corps Captain in the U.S. Air Force. He and Beverly moved to Laughlin Air Force Base in Texas, where they welcomed their first child, David. After completing his military service in 1957, they relocated to Oregon, where Del continued to advance his medical career and became the proud father of twins, Mary and Tom.

In 1960, Del joined the pediatric department at the University of Arkansas, and eight years later, he was recruited to head the Division of Pediatric Endocrinology and Metabolism at Harbor-UCLA Medical Center, leading to a move to Palos Verdes Estates, California.

Del made significant contributions to the field of medicine, serving as editor-in-chief for prestigious journals such as the Journal of Clinical Endocrinology and Metabolism and Pediatric Research. In 1991, he took on a new role as head of Reference Laboratories for Nichols Institute (now Quest Diagnostics) and later became VP for Science and Innovation.

Throughout his career, Del was a passionate mentor, fostering international clinical collaboration and cultivating global endocrine expertise. Notably, Dr. Fisher was instrumental in developing a simple, highly effective newborn screening test for congenital hypothyroidism. His visionary efforts enabled early detection and treatment of this condition resulting in the elimination of mental retardation due to this disorder. The implementation of this screening test across all U.S. states stands as a testament to his expertise and dedication to enhancing pediatric health.

Beyond his professional achievements, Del was a loving father and grandfather. He loved traveling, sailing, reading and was a lifelong fitness enthusiast. He is survived by his children, Thomas M. Fisher (Judy) of Del Mar, CA, and Mary Fisher Slater (Rich) of Cheyenne, WY; four grandchildren, Mattie Johnson Gaudern (Mason), Grace Johnson, Robert Slater II, and Chet Slater; two great grandchildren; as well as his brothers Melvin Fisher and Rodney Fisher. He was preceded in death by his wife Beverly Carne Fisher; son David A. Fisher (Donna); granddaughter Sarah Johnson; parents Arthur L. Fisher and Thelma (Johnson) Fisher; and sister Marcelyn Barraque.

Beverly was the heart and support of the Fisher family. Her love and dedication allowed Del to thrive in his career. Together, they created a beautiful legacy of love and family.

Dr. Delbert Fisher will be deeply missed by all who knew him. His contributions to medicine and his unwavering commitment to his family will forever be remembered.
