Ivan Ivanovich (the Russian equivalent of “John Doe”) was the name given to a mannequin used in testing the Russian Vostok spacecraft in preparation for its manned missions. Ivan Ivanovich was made to look as lifelike as possible, with eyes, eyebrows, eyelashes, and a mouth. He was dressed in a cosmonaut suit and strongly resembled a dead person due to the effect later named uncanny valley. For this reason a sign reading “МАКЕТ” (Russian for “dummy”) was placed under his visor so that anyone who found him after his missions would not think he was a dead cosmonaut or an alien.
