title: Otto Hahn (1879-1968): pioneer in radiochemistry and discoverer of radiotherapeutic mesothorium.
abstract: Otto Hahn was a German innovative chemist. He had discovered various radioactive elements, as well as the nuclear fission. He finally received the Nobel Prize for his participation in the atomic energy project, which Hahn and others considered that could be a factor used for peaceful means like cheap electricity and cheap industrial products. His greatest discovery though in oncology was mesothorium, a radioactive element that had been used to treat all cancer types at the beginning of the 20th century.
