Answer:
Joseph Priestley
As well as being a philosopher, political theorist and dissenting clergyman, Joseph Priestley was the first scientist to discover oxygen. In August 1774, Priestley isolated what he called an ‘air’ that appeared to be completely new. It wasn’t until March 1775 that he wrote to several people about this new air, after conducting experiments into it.
Priestley shut mice in a tight-sealed container filled with the new air and found they could survive longer than with normal air. Although he didn't know it at the time, Priestley had discovered oxygen.
