God invented promethium, specifically in the detonation of various supernovas and during the big bang. Promethium, however, is unstable and radioactive, with short half-life, and all traces of it have long since vanished. (Except, theoretically, for the alpha decay of promethium-145, but that has not been observed in nature.)
Bohuslav Brauner, in 1902, suggested the existance of element 61, when he noted an apparent gap between neodymium and samarium. Henry Moseley, in 1914, confirmed the existence of that gap. At Ohio State University, in 1938, some nuclides were discovered that might have been promethium, but there was insufficient chemical analysis to confirm that. At Oak Ridge National Laboratory, in 1945, the first promethium was synthesized and "discovered", as a result of nuclear fission. The team that did this was composed of Jacob Marinsky, Lawrence Glendenin, and Charles Coryell.
