Who Got There Before Gagarin?

From  “The Haunting Mystery Of The USSR’s Lost Cosmonauts“:

In 1961, Cosmonaut Yuri Gagarin became the first man in space. However, some conspiracy theorists speculate that the Soviets reached the cosmos on an earlier mission but covered it up because they lost cosmonauts.

Although, in the grand scheme of things, the USA has lost as many astronauts as Russia.

Russia, though, is the only country to lose astronauts out in space.
