Ivan KonstantinovichAivazovsky, (July 29, 1817 – May 5, 1900) was a painter of an Armenian descent living and working in Crimea, most famous for his seascapes, which constitute more than half of his paintings. Aivazovsky was born in the town of Feodosiya, Crimea (Russian Empire) to a poor Armenian family. His parents' surname was Aivazian. Some of artist's paintings bear the signature, in Armenian letters, «HovhannesAivazian» . His talent as an artist earned him sponsorship and entry to the Simferopol gymnasium №1 and later the St.Petersburg Academy of Arts, from which he graduated with a gold medal. Earning awards for his early landscapes and seascapes, he went on to paint a series of portraits of Crimean coastal towns before travelling throughout Europe.
