Artist Leon Gilmour attended a lecture discussing Einstein's theories and the atom in the 1930s and was inspired by the potential of humanity to harness new ideas to create a better world. He made Outposts in 1936 as a testament to this belief. After the Trinity nuclear weapons tests in 1945 and the bombing of Hiroshima and Nagasaki, Gilmour became disillusioned by humanity's capacity to turn these discoveries into destructive forces. Gilmour's concern about nuclear war continues, as does worry of how to dispose of radioactive materials. ISU sent 4 cubic feet of radioactive waste to the Maxey Flats Nuclear Disposal Site in Kentucky. Maxey Flats was later found to be leaking radiation and became an EPA Superfund Site.
