Nestor Vasilievich Kukolnik (Russian: Нестор Васильевич Кукольник) (1809–1868) was a Russian playwright and prose writer of Carpatho-Rusyn origin. Immensely popular during the early part of his career, his works were subsequently dismissed as sententious and sentimental. Today, he is best remembered for having contributed to the libretto of the first Russian opera, A Life for the Tsar by Mikhail Glinka. Glinka also set many of his lyrics to music.
Nestor Kukolnik was born on September 8, 1809 in the city of Saint Petersburg in the family of a professor lecturing at the Saint Petersburg Teacher's College. His father, Bazyli Wojciech Kukolnik belonged to the ethnic group of Rusyns (Ruthenians) and came from an old noble family. Graduate of Vienna University, he lectured at Poland. In 1804, Bazyli Wojciech Kukolnik was invited to teach in Russia along with professors Ivan Orlay (Orlay János) and Mikhail Balugjanskij. Among his pupils were Grand Duke Constantine Pavlovich of Russia and Grand Duke Nikolai Pavlovich of Russia, the future emperor Nikolai I of Russia; Czar Alexander I of Russia granted Vasily Kukolnik an estate in the Vilno Oblast and was Nestor Kukolnik's godfather at his baptism.
Nestor studied at the Nizhyn Gymnasium of Higher Sciences (present-day Ukraine), founded earlier by Nestor’s father. Nikolai Gogol studied at the same institution and they both played at the school theater. Kukolnik’s literature activity started in gymnasium, where he wrote his first verses and dramas. After graduating from Nizhyn Gymnasium in 1829, he gave lessons at Vilna (present-day Vilnius, Lithuania) Gymnasium, and in 1831 moved with his brother Platon Kukolnik to Saint Petersburg, where he served at the Ministry of Finance.
