Egan O'Connor

Egan O'Connor, a distinguished writer and editor whose career was marked by a deep commitment to public health and scientific integrity, passed away peacefully at her home on March 14, 2026, with her loving husband, Ray Eidissen, by her side. Born on March 10, 1937, in New York, NY, Egan lived a life characterized by intellectual rigor, generosity, and a remarkable sense of humor.

Egan was the daughter of Hugh and Hope O'Connor. Her father, born in 1896, served with distinction as a leader of an artillery brigade in the cavalry during World War One. Between the two world wars, he dedicated 25 years to journalism at The New York Times, establishing a legacy of thoughtful reporting and insight. Her mother devoted her career to education, teaching English and remedial reading at private girls’ schools in Connecticut and Washington, DC, shaping young minds with patience and dedication.

Egan herself pursued an accomplished academic path, attending Smith College and later earning a Master's degree from American University in Washington, DC. Her intellectual pursuits laid the foundation for a career that spanned decades and crossed significant social and professional boundaries.

Beginning her professional journey in the early 1960s, Egan secured a role as a staff member for a West German documentary film company in Washington, DC—an achievement notable at a time when women’s participation in influential professional roles was far less common. Her career evolved as she became a key staffer for Senator Mike Gravel of Alaska, focusing on the critical task of ensuring the safety of nuclear power plants, a reflection of her dedication to public welfare and responsible governance.

In the following years, Egan moved to San Francisco, where she spent 25 years as a writer and editor devoted to supporting a prominent scientist and a small nonprofit organization. Their mission was crucial: investigating and mitigating the harmful impacts of radiation exposure on patients undergoing x-rays and advanced imaging procedures. The work carried out under her stewardship had a lasting, positive influence on radiology safety standards, contributing to enhanced protocols that protect countless patients.

Throughout her life, Egan was known not only for her professional accomplishments but also for her warmth and vitality. She was well educated, intelligent, generous, and incredibly fun—qualities that endeared her to friends and colleagues alike.

Egan is survived by her husband, Ray Eidissen of Seneca; her sister, Delia O'Connor; and her brother-in-law, Dr. Tom O'Neil both of Newburyport, MA. The family was a central part of her life and shared in her many joys and achievements.

Her parents, Hugh and Hope O'Connor, preceded her in death.

A funeral service will be held on March 20, 2026, at 2:00 PM at Ramsey Creek Preserve, located at 390 Cobb Bridge Road, Westminster, South Carolina 29693. The service will celebrate Egan’s rich life and enduring contributions to society.

Egan O'Connor’s legacy is one of intellect, dedication, and compassion—a testament to a life lived with purpose and grace. She will be remembered fondly by all who had the privilege of knowing her.
