This identification badge (2 1/2" x 1 3/4") was used by Glenn Seaborg during his WW II visits to Clinton Laboratories, now known as Oak Ridge National Laboratory. The six inch slide rule (bamboo) was made for the Frederick Post Company by Hemmi of Japan. While it has the model number 1444 stamped on it, the leather case says 1444P. I do not know when Seaborg first used it. Possibly in the 1940s or so. Glenn Seaborg (1912-1999) Nobel Prize in Chemistry in 1951. Discoverer or co-discoverer of ten elements (plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium and seaborgium), and dozens of radionuclides (e.g., Cs-137, Co-60, I-131). He developed the concept of the actinide series which he positioned underneath the lanthanide series on the periodic table. Seaborg actually held patents on the elements americium and curium. He served as the Chairman of the US Atomic Energy Commission from 1961to 1971. Donated by Glenn Seaborg |
