Hans Bethe

German-American physicist (1906–2005)

Hans Albrecht Eduard Bethe (German: [ˈhans ˈbeːtə] ; 2 July 1906 – 6 March 2005) was a German-American physicist who made major contributions to nuclear physics, astrophysics, quantum electrodynamics and solid-state physics, and received the Nobel Prize in Physics in 1967 for his work on the theory of stellar nucleosynthesis. For most of his career, Bethe was a professor at Cornell University. In 1931, Bethe developed the Bethe ansatz, which is a method for finding the exact solutions for the eigenvalues and eigenvectors of certain one-dimensional quantum many-body models.
