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. A month short of 26 years old at launch, he was the youngest person to fly in space until 2021 when Oliver Daemen flew on Blue Origin NS-16 at the age of 18. Since Daemen flew a suborbital mission, Titov remains the youngest man to fly in Earth orbit.
Titov's flight finally proved that humans could live and work in space. He was the first person to orbit the Earth multiple times, the first to pilot a spaceship and to spend more than a day in space. He was also the first to sleep in orbit and to suffer from space sickness.
Titov was the first photographer from space: he made the first manual photographs from orbit, thus setting a record for modern first photos of Earth from space. He also was the first person to film the Earth using a professional quality Konvas-Avtomat movie camera, which he used for ten minutes.
