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 as Los Alamos was being established for the Manhattan Project during World War II, Molly became part of the generation whose quiet dedication helped build one of the most important scientific institutions in our nation's history.

From her modest home in Española, Molly made the familiar drive up "the Hill" to Los Alamos each morning—a journey thousands of Northern New Mexicans have made in service to the Laboratory. Through changing seasons, historic milestones, and generations of scientific advancement, she faithfully made that journey for 54 years.

Even after retiring with 20 years of Federal service, the Lab called Molly back to work two more times because of her experience, work performance, and unwavering commitment to the mission. She never sought recognition. She simply answered the call, serving with humility, professionalism, and quiet excellence through decades of scientific discovery, national security, and public service.

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.
