Curium is undetected in nature, but it was discovered in 1944 at the University of Chicago by Glenn T. Seaborg, Ralph A. James, and Albert Ghiorso in plutonium-239 that had been bombarded by helium ions. Uses -   thermoelectric power, neutron source, was the alpha particle source for the Alpha Proton X-ray Spectrometer on Mars
