<- that is the man who discovered Hydrogen, H2o, it was first generated and described by Paracelsus, who was T. Von Hohenlohe (1493 to 1541). He reacted strong acids with metals to produce it. Credit for the discovery of hydrogen is usually ascribed to Henry Cavendish, who produced it, discovered it burned and produced water upon combustion, and also proposed it was a unique element, which he died in 1776.
Fact!
The Space Shuttle Main Engine burnt hydrogen with oxygen, producing a nearly invisible flame at full thrust.
