Edward Teller

Edward Teller (Hungarian: Teller Ede; 15 January 1908 – 9 September 2003) was a Hungarian-American theoretical physicist and chemical engineer. He is often called "the father of the hydrogen bomb" because he helped create a powerful type of nuclear weapon. Teller was born in Austria-Hungary in 1908 and moved to the United States in the 1930s, joining a group of talented scientists known as the "Martians".

Teller made many important discoveries in physics and chemistry. He helped explain how certain types of radioactive decay work and contributed to theories that are used to study molecules and their properties. During World War II, Teller was part of the Manhattan Project, the effort to build the first atomic bomb. After the war, he pushed hard to develop even more powerful weapons using a process called fusion, which led to the creation of the hydrogen bomb.

Teller also helped start the Lawrence Livermore National Laboratory and worked there for many years. He supported the use of nuclear power and testing, and he even suggested using very large explosions to build things like harbors. Later in life, he advised leaders on many scientific and military projects. Teller received important awards for his work and passed away in 2003 at the age of 95.

Early life and work

Ede Teller was born on January 15, 1908, in Budapest, which was then part of Austria-Hungary. He grew up in a Jewish family and went to the Minta Gymnasium in Budapest. Teller was very interested in numbers and enjoyed doing calculations in his head.

Teller moved from Hungary to Germany in 1926. He studied mathematics and chemistry at the University of Karlsruhe (TH) and later switched to physics after hearing lectures by Herman Mark. He then studied at the Ludwig-Maximilians-Universität München under Arnold Sommerfeld. In 1928, he had an accident where he almost lost his foot, but he learned to cope with the pain without painkillers. He finished his studies at Leipzig University, getting his PhD in 1930.

In 1930, Teller moved to the University of Göttingen, but left Germany when it became unsafe for Jewish people after Adolf Hitler came to power. He went to England and then to Copenhagen to work with Niels Bohr. In 1935, he moved to the United States and became a professor at George Washington University. There, he made important discoveries in physics and became a United States citizen in 1941.

Manhattan Project

Los Alamos Laboratory

In 1942, Edward Teller joined a planning session led by Robert Oppenheimer at the University of California, Berkeley. This session was part of the Manhattan Project, the effort to build the first nuclear weapons in the United States. Teller was very interested in the idea of creating a much bigger bomb than the atomic bomb, called the “Super,” which later became known as the hydrogen bomb.

Construction began on a special laboratory in Los Alamos, New Mexico, in early 1943. Oppenheimer directed this laboratory, whose goal was to design an atomic bomb. Teller moved there in March 1943 and joined the Theoretical Division. He worked on different ideas for building bombs, including one where the bomb’s power would grow as it exploded. Although this idea didn’t work, Teller kept pushing for research into the bigger hydrogen bomb, even when it wasn’t the main focus.

Teller helped with important parts of the bomb design, such as suggesting a better way to build the center part of the bomb. He was one of the few scientists who watched the first nuclear test in July 1945 safely. He described the moment as very bright, like sudden daylight in a dark room.

Hydrogen bomb

Main article: History of the Teller–Ulam design

Edward Teller returned to Los Alamos in 1950 to help create a powerful new kind of bomb. With scientist Stanislaw Ulam, he developed a new design in 1951. This design used a smaller explosion to start a bigger one, making a very powerful bomb possible.

Teller became known as a key person in creating this new bomb design. However, not everyone agreed on who contributed what to the idea. Some said Ulam had the main idea, while others credited Teller. Regardless, the new design was seen as a major breakthrough, and both the United States and the Soviet Union began working on similar weapons.

Oppenheimer controversy

In 1954, Edward Teller became involved in a big debate when he spoke about J. Robert Oppenheimer during a hearing to decide if Oppenheimer could keep his security clearance. Teller and Oppenheimer had disagreed many times before, especially about work on new types of energy weapons. During the hearing, Teller said he did not think Oppenheimer should keep his security clearance because he did not trust his decisions.

Many of Teller’s science friends did not agree with what he said, and he became isolated from the science community. Teller later said he did not mean to hurt Oppenheimer, but his words had a big impact. Some believe Oppenheimer would have lost his clearance no matter what, but Teller’s comments made him a target for blame.

US government work and political advocacy

After some scientists had disagreements, Edward Teller continued to work closely with the government. He supported the development of safe nuclear reactors and helped create designs that could prevent dangerous accidents. His ideas were used in hospitals and universities around the world.

Teller also believed in strong defense and spoke up about the need for more spending to protect the country. He worked on important projects involving nuclear weapons and served in many leadership roles at science labs and universities. He was very active in advising leaders about nuclear testing and policy.

Global climate change

Edward Teller was one of the first well-known people to talk about the dangers of climate change. He said that burning fossil fuels adds carbon dioxide to the air, which acts like a blanket and makes the Earth warmer.

In 1957, Teller told a group of scientists that if the amount of carbon dioxide in the air went up by 10%, it could melt some of the polar ice. Later in 1959, he spoke at an event about oil and warned that burning fuels creates carbon dioxide. He explained that this gas traps heat and could raise temperatures enough to melt ice caps, which might flood cities near the coast.

Non-military uses of nuclear explosions

Edward Teller strongly supported looking into ways to use nuclear explosions for jobs that were not related to war. The United States looked into this idea under something called Operation Plowshare. One big plan he suggested was to use a very powerful hydrogen bomb to dig a deep-water harbor in Point Hope, Alaska. This harbor would be more than a mile long and half a mile wide, to help move resources from coal and oil fields. The government agreed to look into this plan in 1958, calling it Project Chariot. Teller talked about how much money this could save, but he couldn’t convince local leaders it was a good idea.

Some scientists worried this plan could hurt animals and the Inupiat people who lived nearby. They weren’t told about the plan until 1960. The harbor would also be blocked by ice for nine months every year. Because of these problems and worries about health, the project was stopped in 1962.

Teller also supported another idea: using nuclear explosions to get oil from tar sands in northern Alberta. This was called Project Oilsands. The government of Alberta liked the idea, but Canada’s government, led by Prime Minister John Diefenbaker, said no because they didn’t want nuclear weapons in Canada. Later, Canada did agree to have nuclear weapons from the United States from 1963 to 1984.

Teller also suggested using nuclear bombs to stop big storms called hurricanes. He thought that by setting off nuclear explosions in the right places, we could create many small storms instead of one big one.

Nuclear technology and Israel

For many years, Edward Teller gave advice to Israel about nuclear energy, especially about making a very powerful bomb. In 1952, he met with a leader of Israel and shared ideas about how to create special materials needed for nuclear reactions. Starting in 1964, Teller visited Israel many times, giving talks and sharing his knowledge with important leaders there.

Later, Teller shared with American leaders that Israel had built nuclear weapons, explaining that this was needed because of a big war. He also helped stop American plans to check Israel's nuclear facilities. Even years later, Teller confirmed that Israel had these powerful weapons but had not tested them, knowing that testing could cause problems.

Three Mile Island

Edward Teller had a health issue in 1979 and felt it was because of Jane Fonda. She had acted in a movie called The China Syndrome, which showed a made-up accident at a nuclear plant. The movie came out just before a real accident happened at Three Mile Island. After this accident, Teller worked hard to support nuclear power, saying it was safe and reliable. He even wrote an article in The Washington Post saying he was the “only victim” because of the stress from defending nuclear power, not the accident itself.

He believed reactors were not dangerous and that his health issue was due to the stress of talking against people like Ralph Nader and Jane Fonda who were speaking out against nuclear power.

Strategic Defense Initiative

In the 1980s, Edward Teller strongly supported an idea called the Strategic Defense Initiative, which critics called "Star Wars." This plan aimed to use lasers, particle beams, and missiles—both on the ground and in space—to stop enemy missiles before they could reach the United States. Teller worked with government leaders, including President Ronald Reagan, to start research on this defense system. The idea was to use special satellites with atomic weapons to shoot X-ray lasers at incoming missiles.

Some scientists thought the plan wouldn’t work. They believed that an enemy could use simple tricks to avoid the defense system without spending much money. Teller wrote a book in 1987 called Better a Shield than a Sword to explain his support for protecting people and using active defense systems. His ideas about lasers were shared in conferences in 1986 and 1987.

Asteroid impact avoidance

After seeing the 1994 impacts of the comet Shoemaker-Levy 9 with Jupiter, Edward Teller suggested a way to protect Earth from big space rocks. He spoke to scientists from the United States and Russia who used to design weapons during the Cold War. They met at the Lawrence Livermore National Laboratory in 1995 to talk about planetary defense.

Teller proposed using a very powerful explosion, about as strong as a million tons of dynamite, to stop a big asteroid from hitting Earth. This explosion would weigh about as much as a small truck—light enough to be launched into space by the Russian Energia rocket. If scientists saw a dangerous asteroid far enough in advance, they could use this explosion to either vaporize it or change its path so it misses Earth. This idea could even help against very rare and huge space objects, including some comets that come from far away in space.

Death and legacy

Edward Teller passed away in Stanford, California on September 9, 2003, at the age of 95. He had health problems related to his age and had a medical event two days before he died.

Teller strongly supported having strong defenses using nuclear technology. Because of this, some people thought of him as a character from stories about scientists who make bad choices. He received many awards for his work, including the National Medal of Science and the Presidential Medal of Freedom. He was also recognized by science groups and received special honors from leaders and organizations.

Publications

Edward Teller wrote many books about science and energy. Some of his well-known books include Our Nuclear Future; Facts, Dangers, and Opportunities from 1958, Basic Concepts of Physics from 1960, and The Legacy of Hiroshima from 1962. He also wrote The Constructive Uses of Nuclear Explosions in 1968 and Energy from Heaven and Earth in 1979. Later, he published Better a Shield Than a Sword in 1987 and Conversations on the Dark Secrets of Physics in 1991. His memoirs, titled Memoirs: A Twentieth-Century Journey in Science and Politics, came out in 2001.
