Viktor Ambartsumian was born in then-Soviet Georgia and educated at the University of Leningrad, now St. Petersburg State University. He worked at the Pulkovo Observatory, the Byurakan Astrophysical Observatory (BAO), which he founded and directed, Erevan University, and the Armenian Academy of Sciences, which he served as president from 1947 to 1993. While at Pulkovo he also taught at the University of Leningrad, where he was appointed professor at age 26, and wrote the first Russian textbook on theoretical astrophysics. Most of his research was devoted to invariance principles applied to the theory of radiative transfer, inverse problems of astrophysics, and the empirical approach to the problems of the origin and evolution of stars and galaxies. He was first to suggest that T Tauri stars are very young and to propose that nearby stellar associations are expanding. He also showed that evolutionary processes such as mass loss are occurring in galaxies. He worked on interstellar matter, showing that it is in clouds, radio galaxies, and active galactic nuclei. He was the founding editor-in-chief (1964-87) of Astrofizika, which became the leading astronomy publication in the Soviet Union. He served as president of the International Astronomical Union, and he hosted conferences on the search for extraterrestrial civilizations. Note: His first name is sometimes spelled Victor, and his last name Ambartsumyan or Ambarzumyan. The only correct spelling is in the Armenian alphabet.
