Ivan Nikolayevich Kudryavtsev (Russian: Иван Николаевич Кудрявцев; 13 April 1904 — 13 August 1995) was a Soviet and Finnish architect, architectural historian, and teacher.
Kudrjavzev was born in St. Petersburg into the family of the hereditary architect Nikolai Galaktionovich Kudryavtsev, builder of the Kazan Cathedral in the city of Luga.
The architecture of Kudrjavzev's buildings was characteristic of the 1930s as an example of Art Deco - a kind of symbiosis of constructivist methods and shaping techniques, definitely associated with the classical tradition.
Having mastered Swedish, he entered the service of the Paul Buman company as a draftsman, which was engaged in engineering equipment, interior design, and furnishing.
He designed the Elias Church at the Orthodox cemetery in Helsinki (1951–1953),[2] the Transfiguration Cathedral of the New Valamo Monastery in Heinävesi (1975–1977),[3] and the temple in the city of Järvenpää (1979–1980).
