Odessa I. I. Mechnikov National University (Ukrainian: Одеський національний університет імені І. І. Мечникова, Russian: Одесский национальный университет имени И. И. Мечникова) is one of Ukraine's major universities, named after the scientist Élie Metchnikoff (who studied immunology, microbiology, and evolutionary embryology), a Nobel prize winner in 1908. The university was founded in 1865, by an edict of Tsar Alexander II of Russia reorganizing the Richelieu Lyceum of Odessa into the new Imperial Novorossiya University. In the Soviet era, the University was renamed Odessa I. I. Mechnikov National University (literally, "Odessa National University named after I. I. Mechnikov"). Odessa I. I. Mechnikov National University comprises four institutes, ten faculties, and seven specialized councils. The University is famous for its scientific library, the largest and oldest of any university in Ukraine (3,600,000 million volumes, ranging from the 15th century to the present day).
