Rolf Landauer, a German-American physicist, emigrated to the U.S. in 1938. He obtained a Ph.D. in physics from Harvard in 1950 and spent most of his career at IBM. In 1961, he discovered Landauer's principle, which states that in any operation manipulating information, entropy increases and energy is dissipated as heat. He also developed the Landauer formula connecting electrical resistance to scattering properties. Landauer's work has implications for reversible computing, quantum information, and quantum computing. He received prestigious awards for his contributions to physics.

Konrad Dannenberg was a German-American rocket pioneer who played a pivotal role in the development of space exploration. As a member of the German rocket team brought to the United States after World War II, Dannenberg made significant contributions to the American space program. He was involved in the development of important projects such as the Saturn V rocket, which was crucial in the Apollo moon missions. Dannenberg's expertise and dedication helped advance rocket technology and shape the future of space exploration.
