Question: Frederic de Hoffmann assisted which Hungarian-American physicist in the development of the hydrogen bomb?

Related documents: [0]  [DOC] Frederic de Hoffmann (b. Vienna, July 8, 1924 – d. La Jolla, October 4, 1989) was a nuclear physicist who worked on the Manhattan Project. He came to the United States of America in 1941 and graduated from Harvard in 1944. Upon graduating, de Hoffmann was sent to Los Alamos National Laboratory where he assisted Edward Teller in the development of the Hydrogen bomb. Frederic de Hoffmann was an advocate of peaceful atomic energy. [END] 
[1]  [DOC] Edward Teller (Hungarian: "Teller Ede" ; January 15, 1908 – September 9, 2003) was a Hungarian-American theoretical physicist who was born in Hungary, and is known colloquially as "the father of the hydrogen bomb", although he claimed he did not care for the title. He made numerous contributions to nuclear and molecular physics, spectroscopy (in particular the Jahn–Teller and Renner–Teller effects), and surface physics. His extension of Enrico Fermi's theory of beta decay, in the form of Gamow–Teller transitions, provided an important stepping stone in its application, while the Jahn–Teller effect and the Brunauer–Emmett–Teller (BET) theory have retained their original formulation and are still mainstays in physics and chemistry. Teller also made contributions to Thomas–Fermi theory, the precursor of density functional theory, a standard modern tool in the quantum mechanical treatment of complex molecules. In 1953, along with Nicholas Metropolis, Arianna Rosenbluth, Marshall Rosenbluth, and Augusta Teller, Teller co-authored a paper which is a standard starting point for the applications of the Monte Carlo method to statistical mechanics.
