Polonium was discovered by Marie Curie and Pierre Curie in 1898.
Bequerel was the first to note radioactivity, in 1896. Curie discovered radium in 1898, after experiments with uranium and then pitchblende.
Marie Curie did not invent radium and polonium; she discovered them. It took several years of intense research for Curie, along with her husband Pierre Curie, to isolate and identify these radioactive elements in 1898.
Marie Curie received her second Nobel Prize in 1911 for the discovery of radium and polonium, specifically in the field of Chemistry. She remains the only person to have received Nobel Prizes in two different scientific fields.
The year was 1898; the first experimental results in April, a published article in July 1898.

Polonium was discovered in 1898 by Pierre Curie and Marie Curie, in a Paris laboratory.
Polonium and was discovered in 1898 by Pierre Curie and Marie Curie.
Polonium was discovered by Marie Curie and Pierre Curie in 1898.
Polonium was discovered by Marie and Pierre Curie in 1898, who were studying the residues of uranium pitchblende (after uranium separation) from Jachymow; the residue has a greater radioactivity than uranium.
In 1898
Chemical elements are not invented; they are discovered or prepared.Polonium was discovered (not invented) by Marie Curie and Pierre Curie in 1898.
Bequerel was the first to note radioactivity, in 1896. Curie discovered radium in 1898, after experiments with uranium and then pitchblende.
Marie Curie and Pierre Curie found after studying residues of uranium ores that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
