He later attended the Institute of Fine Arts in Cairo and then was granted scholarship to attend Académie de la Grande Chaumière in Paris. He also studied at the studio of renowned painter Andre L’Hote during his stay in Paris.
He took on his early education at Melkonian Armenian school in Cyprus. His early works are small-size oils: one-figure compositions in interiors and still lifes. His personages are social or occupational types, static figures circumscribed by a space limited in depth, their mood of constraint and isolation suggest a miserable existence.
Hagopian had several exhibitions in Yerevan, Moscow, and other cities.
He died in Yerevan, aged 89.
Participant of a massive mid-20th century wave of Armenian exiles and their families returning to their familial homeland, Hagopian immigrated to the Soviet Union to settle in the Armenian Soviet Socialist Republic in 1962, and his new world became the Armenian landscape.
