Glenn Seaborg and Helen Griggs Seaborg had seven children, of whom the first, Peter Glenn Seaborg, died in 1997 (his twin Paulette having died in infancy). [56] The others were Lynne Seaborg Cobb, David Seaborg , Steve Seaborg, Eric Seaborg, and Dianne Seaborg.
Feb 25, 1999 · They have six children: Peter (b. 1946), Lynne (b. 1947), David (b. 1949), Stephen (b. 1951), John Eric (b. 1954), and Dianne (b. 1959). His chief hobby is golf, but he also follows other sports with interest.
Glen T. Seaborg was a Swedish-American nuclear chemist who won the Nobel Prize in chemistry for the discovery of ‘Plutonium’. This biography provides detailed information about his childhood, life, career, research, achievements and timeline.
Glenn T. Seaborg (born April 19, 1912, Ishpeming, Michigan, U.S.—died February 25, 1999, Lafayette, California) was an American nuclear chemist best known for his work on isolating and identifying transuranium elements (those heavier than uranium).

Working with John J. Livingood, Seaborg discovered iodine-131 and cobalt-60: these are crucial radioisotopes in medical diagnoses and treatments. In 1938, Seaborg and Emilio Segrè discovered technetium-99m, the most-used medical radioisotope ever. It is used it tens of millions of scans every year.
In 1940, Edwin McMillan and Philip Abelson discovered element 93 using the 60-inch cyclotron at the Lawrence Radiation Laboratory, Berkeley. They named the new element neptunium, after the planet Neptune. Their discovery depended on work Seaborg and his colleagues carried out on a method to isolate the new radioactive metal. Soon after his discover...
After discovering plutonium, Seaborg’s team continued working with the 60-inch cyclotron, discovering curium (in 1944), americium (in 1944), and berkelium (in 1949). Seaborg became a full professor of chemistry in 1945. Seaborg co-discovered californium in 1950 and mendelevium in 1955 using the 60-inch cyclotron. He also co-discovered the new eleme...
Seaborg moved to Chicago where he led a team of 100 scientists who worked out how to refine plutonium from uranium and produce it in viable quantities for a plutonium based atomic bomb. Seaborg was one of the scientists who put their name to the Franck Report, a secret document requesting that the bomb should not be used as a weapon. The scientists...
On the basis of electron structures, in 1944 Seaborg proposed that a new row should be added to the periodic table. The new row would be placed below the row of elements known as the lanthanides. The elements in Seaborg’s new row would be called the actinides. He was warned it would ruin his scientific reputation to publish such a proposal, but he ...
These were mainly for methods of processing and separating radioactive heavy elements. He also patented methods for producing and separating the element americium. Royalties from the americium patents provided him with an ongoing income after americium became a standard part of smoke detectors.
Seaborg predicted the existence of heavier elements than the ones he discovered. These new elements would, he said, be very unstable, with half-lives measured in seconds or fractions of seconds. He also predicted some superheavy elements would form an ‘island of stability’ in the periodic table, with much longer half-lives than surrounding elements...
Seaborg was awarded the Nobel Prize in Chemistry in 1951, when he was just 39 years old. Seaborg shared the prize with Edwin McMillan for their work in discovering elements heavier than uranium. Recipients of the prize travel to Sweden’s capital, Stockholm, to receive their awards. Brought up by parents who spoke Swedish at home, Seaborg is one of ...
From 1961 to 1971 Seaborg chaired the Atomic Energy Commission. In this role he helped negotiate the Limited Test Ban Treatysecuring the agreement of the US, UK, and USSR in banning above-ground testing of nuclear weapons.
Seaborg’s achievements and activities thrust his name into the Guinness Book of World Records for taking up the most space in Who’s Who in America: more than any actor, sports star or even politician!
Shortly after he joined the Manhattan Project in 1942 he married Helen L. Griggs, then secretary to Nobel Laureate E.0. Lawrence. They now have four children Peter Glenn, Lynne Annette, David Michael, and Stephen Keith. Dr. Glenn Seaborg with Ion-Exchanger illusion column of actnide elements, May 19, 1950.
