High Quality Content by WIKIPEDIA articles! Yefgraph Dmitrievich Tyurin (Russian: Евграф Дмитриевич Тюрин) was a Russian architect and art collector, famous as the builder of Elokhovo Cathedral in Moscow, the main cathedral of Russian Orthodox Church in 1945–2000, and Moscow State University expansion in 1830. Tyurin’s life and work, especially in his later years, was poorly documented. His life period is usually presented as 1792–1870, however, recent studies by Sophia Tyurina-Mitrokhina extend it, most likely, to 1793–1875.
