Los Alamos Nuclear Forum 2026
Dedicated to the Memory of
Ercilia Roybal Mollahan
"Molly"
October 7, 1912 – August 31, 2008
A Daughter of Northern New Mexico.
A Woman of the Manhattan Project Generation.
A Legacy That Endures.
The Los Alamos Nuclear Forum is dedicated to the Manhattan Project Generation—the scientists, engineers, technicians, laborers, construction workers, craftspeople, administrators, managers, supervisors, security personnel, and families of Northern New Mexico whose dedication, sacrifice, and service built Los Alamos and laid the foundation for America's nuclear leadership.
We especially honor one of those remarkable individuals—Ercilia "Molly" Roybal Mollahan—whose 54 years of faithful service exemplified the character, humility, and quiet commitment that continue to define Los Alamos today.
When the United States Called, New Mexico Answered
Recruited by the U.S. Army in Santa Fe during World War II, Molly began her service as Los Alamos was being established as the secret scientific laboratory of the Manhattan Project.
She was part of a generation of Northern New Mexicans whose quiet dedication helped build one of the most important scientific institutions in our nation's history.
Following the war, Los Alamos transitioned to the newly established U.S. Atomic Energy Commission (AEC), where Molly continued her career and completed 30 years of federal service.
From her home in Española, Molly made the familiar drive up "the Hill" each morning, serving through historic milestones and generations of scientific advancement.
After retiring from federal service, Molly felt the call to return back to work at Los Alamos Scientific Laboratory—now Los Alamos National Laboratory—because of her experience, work ethic, and commitment to the mission. She ultimately completed an extraordinary 54 years of total service.
Molly never sought recognition. She simply answered the call—serving with humility and quiet excellence from the Manhattan Project era through decades of scientific discovery, national security, and public service at Los Alamos.
Molly's Story Is the Story of Northern New Mexico
From Española, Santa Fe, Pojoaque, Nambe, Chimayó, El Rancho, San Ildefonso Pueblo, Santa Clara Pueblo, Ohkay Owingeh, Abiquiu, Jemez Pueblo, Taos, Truchas, Peñasco and communities throughout Northern New Mexico, generations of local families answered the call to serve. They became the backbone of Los Alamos—scientists, engineers, technicians, laborers, construction workers, craftspeople, administrators, managers, supervisors, security personnel, and support staff—whose dedication made every breakthrough, every innovation, and every mission possible.
History rightly remembers the visionary scientists whose discoveries changed the world. But Los Alamos was built—and continues to be sustained—by thousands of New Mexicans whose names may never appear in history books, yet whose dedication, craftsmanship, and commitment made those achievements possible.
Molly was one of those extraordinary people.
A Legacy Spanning Four Generations
Her commitment to service became the foundation of a family legacy that continues to this day.
Her children followed in her footsteps. Her grandchildren continued that tradition. Today, three of her great-grandchildren continue serving at Los Alamos National Laboratory, carrying forward a tradition of service that now spans four generations.
As Molly's grandson, I can think of no more meaningful tribute than to dedicate the Los Alamos Nuclear Forum to her memory—and to every Northern New Mexico family whose generations of service have quietly shaped the Laboratory's history and continue to build its future.
We love you. We honor you. We will carry your legacy forward.
