U.S./rocket March 1961 -- Mannequin Test Flight

Ivan Ivanovich -- the Russian equivalent of John Doe -- was the name given a mannequin launched in a Vostok spacecraft wearing a SK-1 pressure suit. After re-entering the atmosphere, Ivan was ejected from the capsule and parachuted to the ground near the Ural Mountains city of Izevsk. This sort of ejection-and-parachute system was used later by Vostok cosmonauts.
