Why Is Yervant Terzian Influential?
(Suggest an Edit or Addition)According to Wikipedia, Yervant Terzian was an American astronomer. He was the Tisch Distinguished Professor Emeritus in Cornell University's Department of Astronomy, which he chaired between 1979 and 1999. Background Yervant Terzian was born on February 9, 1939, in Alexandria, Egypt to a Greek mother, Maria , daughter of a fisherman, and an Armenian father, Bedros Terzian, a merchant who survived the Armenian genocide. He studied at the Kalousdian Armenian School in Cairo and received his B.Sc. in physics and mathematics from the American University in Cairo in 1960. He then emigrated to the United States and enrolled at Indiana University Bloomington. He received his master's degree in 1963 and completed his Ph.D. in astrophysics in 1965.
