Seaborg Contributions to Advancing Science Courtesy of Lawrence Berkeley National Laboratory Resources with Additional Information Patents - Glenn T. Seaborg, about the naming of Element 106 seaborgium, the first time an element was named for a living person. Glenn T. Seaborg was born April 19, 1912, in Ishpeming, Michigan. He was educated at the University of California (UC), Los Angeles (B.A.) and the University of California, Berkeley (Ph.D.). "His life-long association with the Lawrence Berkeley National Laboratory [LBNL] began in 1934 when, as a graduate student, he went to work at the UC Radiation Laboratory (the forerunner to LBNL). He joined the UC Berkeley faculty in 1939 and, following his time at the AEC [Atomic Energy Commission] helm, returned to Berkeley where he continued his search for new elements and isotopes." th century design, the actinide concept showed how the transuranium elements fit into the periodic table."

Seaborg (right) and his coworkers were trying to learn enough about transuranium chemistry to ensure that plutonium could be chemically separated from the uranium that would be irradiated in a production pile. Using lanthanum fluoride as a carrier, Seaborg isolated a weighable sample of plutonium in August 1942. At the same time, Isadore Perlman and William J. Knox explored the peroxide method of separation; John E. Willard studied various materials to determine which best adsorbed (gathered on its surface) plutonium; Theodore T. Magel and Daniel K. Koshland, Jr., researched solvent-extraction processes; and Harrison S. Brown and Orville F. Hill performed experiments into volatility reactions. Basic research on plutonium's chemistry continued as did work on radiation and fission products. Seaborg's discovery and subsequent isolation of plutonium were major events in the history of chemistry, but it remained to be seen whether they could be translated into a production process useful to the bomb effort. The laboratory process created by Seaborg would have to be scaled-up a

Germantown's Natural History: The Glenn Seaborg Trail The map shows the Glenn Seaborg Trail and forest in relation to the site boundary to the east, the pond to the north, and Interstate 270 to the northeast. For a virtual walk on the Trail, mouse-over the red squares on the map to view a picture; click for a larger picture and description. You may also view the pictures in a slideshow. Glenn T. Seaborg, Nobel Laureate and AEC Chairman from 1961 to 1971, blazed the Trail that bears his name today. An avid hiker, he often walked on the Trail with friends and associates. The Trail is about one quarter mile long from its northern entrance near the newly reforested area to its southern entrance near the Child Development Center. From the northern edge of the forest, the Trail winds past a number of large, ancient trees: a white oak from the 1750s, a tulip poplar from the 1870s and a particularly large white oak from the 1840s. The Trail continues beneath a mix of hickories, oaks, and tulip poplar, ending in an area of Virginia pines from the mid-1950s. Conditions around the AEC site enabled these old trees to survive. Construction of the AEC building in 1956-1957 had minimal impact on the forest. (See
