Roger Sr was a mechanical engineer having graduated from Stanford University during World War II. He and his wife, Katherine Barnes were recruited by the FBI who made contact with them at the Santa Fe training station when they were leaving town, after their honeymoon at Ghost Ranch. Roger’s uncle and aunt, Arthur and Phoebe Pack owned Ghost Ranch. This is documented in the book “They Called it Ghost Ranch.” Roger and Kitty had three children, one of whom was born in 1944 at Los Alamos; the other two shortly after the war ended. Roger worked on the critical assembly for the atomic and hydrogen bombs. He was at Trinity, stationed five miles away with a search light to help track the cloud. And he was at the Bikini atoll for the latter. For his career he worked at the Pajarito Site at Los Alamos, working on advanced technologies to shrink the sizes of nuclear power plants and related nuclear projects .
