Lawrence Glendenin
Lawrence Elgin Glendenin (born November 8, 1918 in Bay City , USA , † November 22, 2008 in Illinois , USA) was an American chemist and co-discoverer of the element promethium .
Glendenin worked in the Clinton Laboratories, now Oak Ridge National Laboratory , studying elements from fission during World War II . He and his two colleagues Jacob A. Marinsky and Charles D. Coryell were able to isolate the previously unknown rare earth metal promethium and also produce it by bombarding neodymium with neutrons . The separation from the other elements formed was carried out by means of ion exchange chromatography .
Glendenin was among the 154 signatories of the Szilárd petition in 1945 . In this petition Harry S. Truman was asked to use the atomic bomb only as a demonstration in an uninhabited area in order to give Japan the possibility of surrender .
A year after receiving his PhD in 1949, he moved to the Argonne National Laboratory where he stayed until 1985.

He received the Glenn T. Seaborg Award for Nuclear Chemistry in 1974.
