Gherman Titov, Russian general, pilot, and astronaut (died 2000)

Gherman Stepanovich Titov was a Soviet and Russian 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 is the youngest professional astronaut and 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 person to fly in Earth orbit.
