George Robert “Bob” Anderson (1847?-1886?) was an early settler in Southern Nevada. He is best known for being the business partner of James Bernard Wilson. On January 31, 1875, they filed the deed to 320 acres located twenty-four miles west of Las Vegas, Nevada at the base of Sand Mountain in Cottonwood Valley. The property formerly known as ‘Williams Ranch’ or ‘Williams Homestead’ was renamed Sandstone Ranch. There they established a working cattle ranch and a goods delivery service.

The Human Radiation Experiments Records (1949-1995) contain reports from the National Environmental Policy Act (NEPA), the Advisory Committee on Human Radiation Experiments (ACHRE), and the U. S. Department of Energy (DOE). Also included are newspaper clippings, a court case brought by the National Association of Radiation Survivors (NARS), and cancer research papers. With the goal of building an atomic bomb using plutonium extracted from uranium, the material also examines the outcomes of radiation exposure done on humans during the late 1940s and early 1950s at the Oak Ridge Nuclear Facility in Tennessee.
