Rosario Martinez Fiorillo grew up in northern New Mexico during the Manhattan Project. Her ancestors were Hispano homesteaders who built the Romero Cabin, an important pre-Manhattan Project structure at Los Alamos.
Elmer began working with the Manhattan Project in 1941. He was one of the first people to arrive at Oak Ridge and experienced first-hand some of the difficulties there with cyclotrons and isotope separation.
