<p>Edward Teller (January 15, 1908 – September 9, 2003) was a Hungarian-born American physicist who is often referred to as the "father of the hydrogen bomb." He made significant contributions to the development of nuclear weapons and was a key figure in the Manhattan Project, the program that developed the first nuclear weapons during World War II.</p><p></p><p>Teller was born in Budapest, Hungary and received his Ph.D. in physics from the University of Leipzig in Germany in 1930. He then worked at the University of Gottingen and later at the Kaiser Wilhelm Institute for Physics in Berlin. In the early 1930s, Teller became interested in the possibilities of nuclear energy and began to work on the theoretical aspects of nuclear physics.</p><p></p><p>In 1935, Teller left Germany and moved to the United States to escape the rise of Nazism. He joined the faculty at George Washington University and later at the University of Chicago. He was involved in the Manhattan Project from its inception, and he made significant contributions to the development of the first nuclear weapons.</p><p></p><p>After World War II, Teller continued to work on nuclear weapons and was a key figure in the development of the hydrogen bomb. He proposed the concept of a "super" bomb, which would use the fusion of hydrogen isotopes to create a much more powerful explosion than a fission bomb. The first hydrogen bomb was tested in 1952.</p><p></p><p>Teller was a controversial figure, and his advocacy for the development of nuclear weapons and his role in the Red Scare of the 1950s led to criticism from some quarters. But Teller's work had an enormous impact on the field of nuclear physics and on the nation's defense. He received numerous awards and honors throughout his career, including the Presidential Medal of Freedom in 2003.</p><p></p><p>Edward Teller was a Hungarian-born American physicist who is widely known as the "father of the hydrogen bomb."
