Glenn Theodore Seaborg (April 19, 1912 – February 25, 1999) was an American
chemist prominent in the discovery and isolation of ten transuranic elements
including plutonium, americium, curium, berkelium, californium, einsteinium,
fermium, mendelevium, nobelium and seaborgium, which was named in his honor.
During the Manhattan Project, he contributed to the the scaling of experiments
to produce larger amounts of plutonium. He was the first to propose the actinide
series in the Periodic Table of the Elements, which led to the current
arrangement of the table. In 1951, Glenn Seaborg and Edwin McMillan shared the
Nobel Prize in Chemistry "for their discoveries in the chemistry of the
transuranium elements." He spent most of his career as an educator and research
scientist at the University of California, Berkeley, where he also served as the
second Chancellor in its history. He was the chairman of the United States
Atomic Energy Commission from 1961 to 1971, and advised ten presidents from
Truman to Clinton in either formal or informal capacities. He contributed to
arms control efforts and was a well-known activist and advocate for education,
especially science education and federal funding for pure research.
Early life
Of Swedish ancestry, Seaborg was born in Ishpeming, Michigan, the son of Herman
Theodore (Ted) and Selma Olivia Erickson Seaborg. He had one sister, Jeanette.
When Glenn Seaborg was a boy, the family moved to the Seaborg Home in a
subdivision called Home Gardens, that was later annexed to the City of South
Gate, California, a suburb of Los Angeles.
He kept a daily journal from 1927 until he suffered a stroke in 1998. As a youth,
Seaborg was both a devoted sports fan and an avid movie buff. His mother
encouraged him to become a bookeeper as she felt his literary interests were
impractical. He did not take an interest in science until his junior year when
he was inspired by Dwight Logan Reid, a chemistry and physics teacher at David
Starr Jordan High School in Watts.
He graduated from Jordan in 1929 at the top of his class and received a bachelor's
degree in chemistry at the University of California, Los Angeles in 1934. While
at UCLA, he was invited by his German professor to meet Albert Einstein, an
experience that had a profound impact on Seaborg and served as a model of
graciousness for his encounters with aspiring students in later years. Seaborg
worked his way through school as a stevedore, fruit packer and laboaratory
assistant. [1]
Graduate work
Ernest O. Lawrence, Glenn Seaborg and Robert Oppenheimer at the controls of the
187-inch cyclotron.He took his doctorate in chemistry at the University of
California, Berkeley, in 1937 with a doctoral thesis on the inelastic scattering
of neutrons in which he coined the term nuclear spallation. He was a member of
the professional chemistry society, Alpha Chi Sigma. As a graduate student in
the 1930s doing wet chemistry research for his advisor Gilbert Newton Lewis,
Seaborg devoured the text Applied Radiochemistry by Otto Hahn, of the Kaiser
Wilhelm Institute for Chemistry in Berlin. For several years, Seaborg conducted
important research in artificial radioactivity using the Lawrence cyclotron at
Cal Berkeley. He was excited to learn from others that nuclear fission was
possible -- but also chagrined, as his own research might have led him to the
same discovery.
Seaborg also became expert in dealing with the great Berkeley physicist Robert
Oppenheimer. Oppenheimer was so quick and knew so much, he had a habit of
answering a junior man's question before it had even been stated. Often the
question answered was more profound than the one asked, but of little practical
help. Seaborg learned to state his questions to Oppenheimer very quickly and
succinctly, and this habit of asking succinct questions stood Seaborg in good
stead all his professional life.
Career
Pioneering work in nuclear chemistry
Seaborg at the Geiger Counter, 301 Gilman Hall, Berkeley, California, where he
discovered plutonium.Seaborg remained at the University of California, Berkeley
for post-doctoral research. He followed Frederick Soddy's work investigating
isotopes and contributed to the discovery of more than 100 isotopes of elements.
Using one of Lawrence's advanced cyclotrons, John Livingood, Fred Fairbrother,
and Seaborg created a new isotope of iron, iron-59 (Fe-59) in 1937. Iron-59 was
useful in the studies of the hemoglobin in human blood. In 1938, Livingood and
Seaborg collaborated to create an important isotope of iodine, iodine-131
(I-131) which is still used to treat thyroid disease. (Many years later, it was
credited with prolonging the life of Seaborg's mother.) As a result of these and
other contributions, Seaborg is regarded as a pioneer in nuclear medicine and is
one of its most prolific discoverers of isotopes. [2]
In 1939 he became an instructor in chemistry at UC Berkeley, was promoted to
assistant professor in 1941 and professor in 1945.
UC Berkeley physicist Edwin McMillan had led a team that discovered Element 93,
neptunium in 1940. However in November 1940, McMillan was persuaded to leave
Berkeley temporarily to assist with urgent research needed to advance radar
technology. Since Seaborg and his colleagues had perfected McMillan's oxidation-reduction
technique for isolating neptunium, he asked McMillan for permission to continue
the research and search for element 94. McMillan agreed to the collaboration.
.[3] Seaborg first reported alpha decay proportionate to only a fraction of the
element 93 under observation. The first hypothesis for this alpha particle
accumulation was contamination by uranium, which produces alpha-decay particles.
However, an analysis of alpha-decay particles ruled out the hypothesis. Seaborg
then postulated that a distinct alpha-producing element was being formed from
element 93. In February 1941, Seaborg and his collaborators made a discovery in
the field of pure scientific research that changed the course of human history
in ways more profound than they could have ever imagined: they discovered
plutonium. In their experiments bombarding uranium with deuterons, they observed
the creation of neptunium, element 93. But it then underwent beta-decay, forming
a new element/plutonium, with 94 protons. Plutonium is fairly stable, but
undergoes alpha-decay, which explained the presence of alpha particles coming
from neptunium.
In the same year in which he produced plutonium, 1941, he also discovered that
the isotope U235 undergoes fission under appropriate conditions. He therefore
contributed to the science enabling two different approaches to the development
of nuclear weapons.
In addition to plutonium, he is credited as a lead discoverer of americium,
curium, and berkelium, and as a co-discoverer of californium, einsteinium,
fermium, mendelevium, nobelium and seaborgium. He shared the Nobel Prize in
Chemistry in 1951 with Edwin McMillan for "their discoveries in the chemistry of
the first transuranium elements." He holds patents on americium and curium,
which were developed in 1944 in Chicago at the wartime metallurgical laboratory
during the Manhattan project. His research contributions to all of the other
elements were conducted at the University of California, Berkeley.
Scientific contributions during the Manhattan Project
On April 19, 1942, Seaborg reached Chicago, and joined up with the chemistry
group at the Metallurgical Laboratory of the Manhattan Project at the University
of Chicago, where Enrico Fermi and his group would later convert U238 to
plutonium in the world's first controlled nuclear chain reaction using a chain-reacting
pile. Seaborg's role was to figure out how to extract the tiny bit of plutonium
from the mass of uranium. Plutonium-239 was isolated in visible amounts using a
transmutation reaction on August 20, 1942 and weighed on September 10, 1942 in
Seaborg's Chicago laboratory. He was responsible for the multi-stage chemical
process that separated, concentrated and isolated plutonium. This process was
further developed at the Clinton Engineering Works in Oak Ridge, Tennessee and
then entered full-scale production at the Hanford Engineer Works, in Hanford,
Washington.
Seaborg's theoretical development of the actinide concept resulted in a
redrawing of the Periodic Table of the Elements into its current configuration
with the actinide series appearing below the lanthanide series. Seaborg
developed the chemical elements americium and curium while in Chicago. He
managed to secure patents for both elements. His patent on curium never proved
commercially viable because of the element's short half-life. Americium is
commonly used in household smoke detectors, however, and thus provided a good
source of royalty income to Seaborg in later years. Prior to the test of the
first nuclear weapon, Seaborg joined with several other leading scientists in a
written statement known as the Franck Report (secret at the time but since
published) calling on President Truman to conduct a public demonstration of the
atomic bomb witnessed by the Japanese rather than engaging in a surprise attack.
Truman instead proceeded to drop two bombs, credited by most observers at the
time with ending the war, a uranium bomb on Hiroshima and a plutonium bomb on
Nagasaki.
Professor and Chancellor at UC Berkeley
After the conclusion of World War II and the Manhattan Project, Seaborg was
eager to return to academic life and university research free from the
restrictions of wartime secrecy. In 1946, he added to his responsibilities as a
professor by heading the nuclear chemistry research at the Lawrence Radiation
Laboratory operated by the University of California on behalf of the United
States Atomic Energy Commission. Seaborg was named one of the "Ten Outstanding
Young Men in America" by the U.S. Junior Chamber of Commerce in 1947 (along with
Richard Nixon and others). Seaborg was elected to the National Academy of
Sciences in 1948. From 1954 to 1961 he served as associate director of the
radiation laboratory. He was appointed by President Truman to serve as a member
of the General Advisory Committee of the Atomic Energy Commission, an assignment
he retained until 1960.
Seaborg served as chancellor at University of California, Berkeley from 1958 to
1961. His term as Chancellor came at a time of considerable controversy during
the time of the free speech movement. In October 1958, he announced that the
University had relaxed its prior prohibitions on political activity on a test
basis. [5] Seaborg served on the Faculty Athletic Committee for several years
and is the co-author of a book concerning the Pacific Athletic Conference
scandal and the founding of the PAC-10 (formerly PAC-8), in which he played a
role. Seaborg served on the President's Science Advisory Commission during the
Eisenhower administration, which produced the report "Scientific Progress, the
Universities, and the Federal Government," also known as the "Seaborg Report,"
in November 1960. The Seaborg Report is credited with influencing the federal
policy towards academic science for the next eight years.
Chairman of the Atomic Energy Commission
President Kennedy and his Atomic Energy Commission Chairman, Glenn Seaborg.After
appointment by President Kennedy and confirmation by the United States Senate,
Seaborg was chairman of the United States Atomic Energy Commission (AEC) from
1961 to 1971. His pending appointment by President Kennedy was nearly derailed
in late 1960 when members of the Kennedy transition team learned that Seaborg
had been listed in a U.S. News and World Report article as a member of "Nixon's
Brain Trust." Seaborg said that as a lifetime Democrat he was baffled when the
article appeared associating him with Vice President Nixon, whom he considered a
casual acquaintance.
While chairman of the AEC, Seaborg participated on the negotiating team for the
Limited Test Ban Treaty (LTBT). Seaborg considered his contributions to the
achievement of the LTBT as his greatest accomplishment. Despite strict rules
from the Soviets about photography at the signing ceremony, Seaborg snuck a tiny
camera past the Soviet guards to take a close-up photograph of President Kennedy
and Soviet Premier Kruschev as they signed the treaty.
Seaborg enjoyed a close relationship with President Johnson and influenced the
administration to pursue the Nuclear Non-Proliferation Treaty.
Seaborg was called to the White House in the first week of the Nixon
Administration in January 1969 to advise President Nixon on his first diplomatic
crisis involving the Soviets and nuclear testing. Seaborg clashed with Nixon
presidential adviser John Ehrlichman over the treatment of a Jewish scientist
whom the Nixon administration suspected of leaking nuclear secrets to Israel.
Seaborg published several books and journal articles during his tenure at the
Atomic Energy Commission. His predictions concerning development of stable
super-heavy elements are considered among his most important theoretical
contributions.[6] Seaborg theorized the transactinide series and the
superactinide series of undiscovered synthetic elements. While most of these
theoretical future elements have extremely short half-lives and thus no expected
practical applications, Seaborg theorized an island of stability for isotopes of
certain elements.
When Seaborg resigned as chairman of the Atomic Energy Commission in 1971, he
had served longer than any other Kennedy appointee.
Return to California
Following his service as Chairman of the Atomic Energy Commission, Seaborg
returned to UC Berkeley where he was awarded the position of University
Professor. At the time, there had been fewer University Professors at UC
Berkeley than Nobel prize winners. He also served as Chairman of the Lawrence
Hall of Science. Seaborg served as President of the American Association for the
Advancement of Science in 1972. Seaborg served as President of the American
Chemical Society in 1976. In 1976, when the Swedish king visited the United
States, Seaborg played a major role in welcoming the king.
In 1980, he transmuted several thousand atoms of lead into gold at the Lawrence
Berkeley Laboratory. His experimental technique, using nuclear physics, was able
to remove protons and neutrons from the lead atoms. Seaborg's technique would
have been far too expensive to enable routine manufacturing of gold from lead,
but his work is the closest to the mythical Philosopher's Stone.
In 1983, President Reagan appointed Seaborg to serve on the National Commission
on Excellence in Education. Upon seeing the final draft report, Seaborg is
credited with making comments that it was far too weak and did not communicate
the urgency of the current crisis. He compared the crisis in education to the
arms race, and stated that we are "a nation at risk." These comments led to a
new introduction to the report and gave the report the famous title which
focused national attention on education as an issue germane to the federal
government.
Seaborg lived most of his later life in Lafayette, California, where he devoted
himself to editing and publishing the journals that documented both his early
life and later career. He rallied a group of scientists who criticized the
science curriculum in the State of California which he viewed as far too
socially oriented and not nearly focused enough on hard science. California
Governor Pete Wilson appointed Seaborg to head a committee that proposed
sweeping changes to California's science curriculum despite outcries from labor
organizations and others.
In 1997, Glenn Seaborg became the Honorary President of the newly formed World
Innovation Foundation. On August 24, 1998, while in Boston to attend a meeting
by the American Chemical Society, Seaborg suffered a stroke, which led to his
death six months later on February 25, 1999.
During his lifetime, Seaborg is said to have been the author or co-author of
more than 50 books and 500 scientific journal articles. He held more than 40
patents — among them the only patents ever issued for chemical elements,
Americium and Curium. He is also said to have received more than 50 degrees and
honorary degrees in his lifetime. At one time, he was listed in the Guinness
Book of World Records as having the longest entry in Marquis Who's Who in
America. In February 2005, after his death, Seaborg was inducted into the
National Inventors Hall of Fame.
Marriage and personal life
Seaborg Family Portrait. From left to right: Lynne Seaborg, Dianne Seaborg,
Peter Seaborg, David Seaborg, Stephen Seaborg (in front of David), Glenn T.
Seaborg, Eric Seaborg (in front of Glenn), and Helen L. Seaborg.In 1942, Seaborg
married Helen Griggs, the secretary of Ernest Lawrence.
Under wartime pressure, Seaborg had moved to Chicago, Illinois while engaged to
Miss Griggs. Seaborg returned to collect Miss Griggs; their friends expected
them to take the train directly from Los Angeles to Chicago, and to get married
in Chicago. But, eager to be married, Seaborg and Griggs impulsively got off the
train in the town of Caliente, Nevada for what they thought would be a quick
wedding.
When they asked for City Hall, they found Caliente had none—they would have to
travel 25 miles north to Pioche, the county seat. With no car, this was no easy
feat but, happily, one of Caliente's newest deputy sheriffs turned out to be a
recent graduate of the Cal Berkeley chemistry department who was only too happy
to do a favor for Glenn Seaborg. The deputy sheriff arranged for the wedding
couple to ride up and back to Pioche in a mail truck. The witnesses at the
Seaborg wedding were a clerk and a janitor.
Glenn Seaborg and Helen Griggs Seaborg had six children, of whom the first,
Peter Glenn Seaborg, died in 1997. The others were Lynne Seaborg Cobb, David
Seaborg, Steve Seaborg, Eric Seaborg, and Dianne Seaborg.
Seaborg was an avid hiker. Upon becoming Chairman of the Atomic Energy
Commission in 1961, he commenced taking daily hikes through a trail which he
blazed at the headquarters site in Gaithersburg, Maryland. He frequently invited
colleagues and visitors to accompany him and the trail became known as the "Glenn
Seaborg Trail."
He and his wife Helen are credited with blazing a 12-mile trail in the East Bay
area near their Lafayette, California home. This trail has since become a part
of the American Hiking Association's cross-country network of trails. Seaborg
and his wife walked the trail network from Contra Costa County all the way to
the California-Nevada border.
Seaborg was honored as Swedish-American of the Year in 1962 by the Vasa Order of
America. In 1991, the organization named "Local Lodge Glenn T. Seaborg No. 719"
in his honor during the Seaborg Honors ceremony at which he appeared. This lodge
maintains a scholarship fund in his name, as does the unrelated Swedish-American
Club of Los Angeles.
Quote
National Commission on Education report in 1983, Glenn T. Seaborg, Chairman.
Our Nation is at risk. Our once unchallenged preeminence in commerce, industry,
science and technological innovation is being overtaken by competitors
throughout the world.... the educational foundations of our society are
presently being eroded by a rising tide of mediocrity that threatens our very
future as a Nation and as a people. What was unimaginable a generation ago has
begun to occur--others are matching and surpassing our educational attainments.
If an unfriendly foreign power had attempted to impose on America the mediocre
educational performance that exists today, we might well have viewed it as an
act of war.
Seaborgium
The element seaborgium was named for him in honor of his accomplishments. It was
so named while he was still alive, which proved extremely controversial. For the
remainder of his life, Seaborg was the only person in the world who could write
his address in chemical element symbols: seaborgium, lawrencium, berkelium,
californium, americium (Glenn Seaborg, Lawrence Berkeley National Laboratory,
Berkeley, California, United States of America), or, in chemical symbols: Sg, Lr,
Bk, Cf, Am. While it is commonly stated that Seaborgium is the only element to
have been named after a living person, this is not entirely accurate. Both
einsteinium and fermium, were proposed as names of new elements discovered by
Albert Ghiorso, Seaborg and the other American co-discoverers of those elements
while Enrico Fermi and Albert Einstein were still living. The discovery of these
elements and their names were kept secret under Cold War era nuclear secrecy
rules, however, and thus the names were not known by the public or the broader
scientific community until after the deaths of Fermi and Einstein. Seaborgium is
the only element to have been publicly named after a living person.
