During the early 20th century, the Russian movement of Cosmism, as represented by Nikolai Fyodorovich Fyodorov, envisioned scientific resurrection of dead people. The idea was so popular that, after Vladimir Lenin's death, Leonid Krasin and Alexander Bogdanov suggested to cryonically preserve his body and brain in order to revive him in the future. Necessary equipment was purchased abroad, but for a variety of reasons the plan was not realized. Instead his body was embalmed and placed on permanent exhibition in the Lenin Mausoleum in Moscow, where it is displayed to this day. The mausoleum itself was modeled by Alexey Shchusev on the Pyramid of Djoser and the Tomb of Cyrus.
