Vitaly Ginzburg

Vitaly Lazarevich Ginzburg (4 October 1916 – 8 November 2009) was a Soviet and Russian theoretical physicist and astrophysicist recognized for foundational contributions to the theory of superconductors and superfluids, work that earned him a one-third share of the 2003 Nobel Prize in Physics jointly with Alexei Abrikosov and Anthony Leggett.

Ginzburg's most influential achievement was the development, in collaboration with Lev Landau, of the Ginzburg–Landau theory in 1950, a phenomenological framework that expanded macroscopic understanding of superconductivity and enabled predictions about superconducting transitions, type-I and type-II superconductors, and later applications to superfluid helium-3. This theory bridged classical and quantum descriptions, facilitating microscopic elaborations by others, including the Nobel co-laureates. Beyond condensed matter physics, Ginzburg advanced radio astronomy and plasma physics through theories of synchrotron radiation from cosmic electrons, radio wave propagation in the ionosphere, and the origins of cosmic radio noise, influencing interpretations of galactic emissions and astrophysical phenomena.

Vitaly Lazarevich Ginzburg was born on October 4, 1916, in Moscow, corresponding to September 21 in the Julian calendar then used in Russia. He was born into a Jewish family as the only child of his parents.

His father, Lazar Efimovich Ginzburg (1863–1942), worked as an engineer specializing in water purification and held several patents in the field. His mother, Avgusta Veniaminovna Vil’dauer-Ginzburg (1886–1920), was a physician born in Mitava (now Jelgava, Latvia). She died of typhoid fever in 1920, when Ginzburg was three years old, during a period of famine and disease following the Russian Civil War.

Following his mother's death, Ginzburg was raised primarily by his father and his maternal aunt, Rosa, the younger sister of Avgusta, who lived with the family and provided care until her own death in 1948. His father later died in 1942 while evacuated to Kazan during World War II.

Vitaly Ginzburg was born on October 4, 1916, in Moscow to a Jewish family; his father, Lazar Efimovich Ginzburg, was an engineer specializing in water purification, and his mother, Avgusta Veniaminovna Vildauer-Ginzburg, was a physician who died of typhoid fever in 1924 when Ginzburg was eight years old, followed by his father's death in 1928. Thereafter, he lived with his aunt, and his parents' decision—exacerbated by the non-compulsory nature of education and concerns over Soviet school quality—delayed his formal schooling until age 11, when he entered the fourth form of School No. 57 in Moscow's Sokolniki district in 1927. He completed the seventh form in 1931 amid Soviet educational reforms that eliminated upper secondary schooling, prompting a brief, disliked stint in vocational training before he secured a position as a laboratory assistant in an X-ray facility at a technical institute under Veniamin Tsukerman and Lev Al'tshuler, an experience that ignited his interest in physics.
