Viktor Ambartsumian

Viktor Ambartsumian was born on September 18, 1908, in Tiflis to an Armenian intellectual family. Educated at Leningrad State University and the Pulkovo Observatory, Ambartsumian became one of the twentieth century's foremost astronomical minds. In 1947, he discovered stellar associations, proving that star formation in galaxies is an ongoing, continuous process rather than a single prehistoric event.

In 1946, he founded the Byurakan Astrophysical Observatory on the slopes of Mount Aragats, establishing Armenia as a world-leading center of observational astronomy. Ambartsumian served as President of the Academy of Sciences of Armenia for four decades and was twice elected President of the International Council of Scientific Unions.
