Edward Teller was a Hungarian-born American theoretical physicist best known for his role in the development of nuclear weapons, especially the hydrogen bomb. He also made important contributions to nuclear and molecular physics, spectroscopy, and surface physics. Teller was a controversial figure in science and politics, and was associated with major U.S. Cold War-era defence policy debates.

Early life and education

Edward Teller was born in Budapest, then part of Austria-Hungary, in 1908. He studied in Germany, earning degrees from the University of Karlsruhe and the University of Leipzig before moving to the United States.

Scientific career

Teller worked in theoretical physics and made lasting contributions to several areas of the field. He is known for work connected to beta decay, the Jahn–Teller effect, and the Brunauer–Emmett–Teller theory.

Manhattan Project and hydrogen bomb

Teller was an early member of the Manhattan Project and later became closely associated with the development of the hydrogen bomb. He and Stanislaw Ulam developed the Teller–Ulam design, which made a practical thermonuclear weapon possible.

Later career and influence

After the war, Teller helped establish Lawrence Livermore National Laboratory and became one of the most influential voices in U.S. nuclear policy. He was also a strong supporter of the Strategic Defense Initiative.

Legacy

Teller remains a significant figure in twentieth-century physics and Cold War history. He is remembered both for scientific contributions and for his controversial political views on nuclear weapons and defence.
