Natural polonium was isolated from residues resulted after the extraction of uranium from ores; the process is long and tedious. Today polonium is obtained artificially.
Marie Curie (from Poland) and Pierre Curie (from France) in 1898.
Of course, many scientists worked with radium and polonium.
Polonium was discovered (not invented) in France by Marie Curie and Pierre Curie in 1898.
Marie Curie
Radium was first isolated in 1898 by Marie Skłodowska-Curie, her husband Pierre Curie, and Gustave Bémont. Marie Curie was born in Poland in 1867. She later became a French citizen. The radioactive element polonium (that she isolated earlier in 1898) is named for her native Poland.
Helped discover Polonium which helped her get the Nobel Prize
Studying residues of uranium ores Marie Curie found that these residues are more radioactive than uranium; she attributed this radioactivity to an unknown element. She isolated this element and named this element polonium.

Studying residues of uranium ores Marie Curie found that these residues are more radioactive than uranium; she attributed this radioactivity to a new element. She isolated this element and named polonium.
Polonium was discovered by Marie Curie and Pierre Curie in 1898. Radium was discovered by Marie Curie, Pierre Curie and G. Bemont also in 1898.
