Lev Davidovich Landau was a prominent Soviet physicist who made fundamental contributions to many areas of theoretical physics. His accomplishments include the independent co-discovery of the density matrix method in quantum mechanics (alongside John von Neumann), the quantum mechanical theory of diamagnetism, the theory of superfluidity, the theory of second-order phase transitions, the Ginzburg–Landau theory of superconductivity, the theory of Fermi liquid, the explanation of Landau damping in plasma physics, the Landau pole in quantum electrodynamics, and the two-component theory of neutrinos. He received the 1962 Nobel Prize in Physics for his development of a mathematical theory of superfluidity that accounts for the properties of liquid helium II at a temperature below 2.17 K (−270.98 °C).

Lyndon Baines Johnson, often referred to as LBJ, was the 36th President of the United States (1963–1969), a position he assumed after his service as the 37th Vice President of the United States (1961–1963). He is one of only four people who served in all four elected federal offices of the United States: Representative, Senator, Vice President and President.
