Ambartsumian, Victor Amazaspovitch
BornTbilisi, (Georgia), 18 September 1908
DiedByurakan, Armenia, 12 August 1996

Some of these ideas, for instance, the unboundedness of many star clusters and the need for star formation to be an ongoing process, have stood the test of time. Others have not.
Victor was the son of Amazasp Asaturovich Ambartsumian, a historian (and, later in life, professor at Yerevan University), and Ripsame Ambartsumian. He married Vera, the adopted daughter of Grigory Shain, the then director of the Crimean Observatory. Victor and Vera had two daughters and two sons.
