The only problem was that those who did so did not recognize the element and did not know it then. Early Detection. This phenomenon of isolating this element and not recognizing it continued even when the man credited for its discovery produced it in an experiment. Carl Wilhelm Scheele was the first to study and isolate chlorine gas. He is credited for its discovery in 1774. However, he did not recognize it as an actual element.
Cavendish also discovered the gas from a certain metal-acid experiment that he performed. Antoine Lavoisier named the gas hydrogen in 1783 when he and Pierre-Simon Laplace proved the findings of Cavendish that water could be produced when the gas is burned. The element was first liquefied in 1898 by James Dewar. He did this with the use of a vacuum flask and the regenerative cooling technique Dewar invented.
