Lev Petrovich Gor'kov (Russian: Лев Петро́вич Горько́в; 14 June 1929 – 28 December 2016) was a Russian-American research physicist internationally known for his pioneering work in the field of superconductivity.[1] He was particularly famous for developing microscopic foundations[2] of the Ginzburg–Landau theory of superconductivity (Vitaly Ginzburg was awarded the 2003 Nobel prize in physics for developing, together with Lev Landau, that phenomenological theory). Gor'kov was a professor of physics at Florida State University in Tallahassee, Florida, and a program director in Condensed Matter at the National High Magnetic Field Laboratory. He was one of the Magnet Lab's founding scientists.
