Gherman Stepanovich Titov was a Soviet cosmonaut who, on 6 August 1961, became the second human to orbit the Earth, aboard Vostok 2, preceded by Yuri Gagarin on Vostok 1. He was the fourth person in space, counting suborbital voyages of US astronauts Alan Shepard and Gus Grissom.
Titov's flight finally proved that humans could live and work in space. He was the first person to orbit the Earth multiple times, to spend more than a day in space, to sleep in orbit and to suffer from space sickness. In fact, he also holds the record for being the first person to vomit in space. He was the first to pilot a spaceship personally and he made the first manual photographs from orbit, thus setting a record for modern space photography. He also was the first person to film the Earth using, for ten minutes, a professional quality Konvas-Avtomat movie camera. A month short of 26 years old at launch, he remains the youngest person to fly in space.
In his subsequent life Titov continued to work for the Soviet space program, playing a major role in the Spiral project where he trained to become the first pilot of an orbital spaceplane.
