Lev Davidovich Landau was a Soviet physicist who made fundamental contributions to many areas of theoretical physics, including superconductivity, superfluidity, and quantum electrodynamics. He was awarded the Nobel Prize in Physics in 1962 for his pioneering theories of condensed matter, especially liquid helium. Landau was also a prolific educator and co-authored a renowned series of textbooks in theoretical physics.
