World-renowned physicist and nuclear scientist Edward Teller passed away on Wednesday, September 9, 2003, at the age of 95. Teller was born on January 15, 1908 in Hungary and, after surviving the Holocaust, obtained a Ph.D. in physics from the University of Leipzig in Germany. He worked in both chemical engineering and mathematical physics at universities in Hamburg, Berlin, and Copenhagen before receiving his greatest opportunity in 1939. That year, Teller left Europe for the United States, where he worked on the top-secret Manhattan Project developing the world’s first atomic bomb. After the war ended, Teller set his mind to developing even more powerful H-bomb weapons, which he saw as necessary deterrents and deterrents against a nuclear attack. He continued working on H-bomb projects for decades afterwards, and was also influential in areas of space exploration and nuclear fusion. Throughout his career, Teller worked with key figures of international science, including Albert Einstein, J. Robert Oppenheimer, Arthur H. Compton, Albertus J. V. de Groot, and Niels Bohr. He published hundreds of books, papers, and essays, and earned numerous awards and honors, most notably the Enrico Fermi Award in 1975. Teller managed to make a significant impact on all areas of science that he pursued, and that legacy will continue to shape the way science moves forward from here. He will be remembered as one of the founding fathers of atomic science.
