Answer:

Marie Curie & Pierre Curie

Step-by-step explanation:

Marie Curie along with her husband Pierre Curie was studying the radioactivity of pitchblende, (also called uranite), the uranium ore

They found that the radioactivity of the pitchblende was radioactive even after removing Uranium and Thorium from it.

In July 1898 they isolated polonium from pitchblende and in December 1898 they isolated radium from pitchblende.

They named polonium after Poland, the homeland of Marie Curie.
