Eka-caesium was discovered in 1939 by Marguerite Perey of the Curie Institute in Paris, France when she purified a sample of actinium-227 which had been reported to have a decay energy of 220 keV.

However, Perey noticed decay particles with an energy level below 80 keV.

Perey thought this decay activity might have been caused by a previously unidentified decay product, one which was separated during purification, but emerged again out of the pure actinium-227.

The new product exhibited chemical properties of an alkali metal ( such as coprecipitating with caesium salts ), which led Perey to believe that it was element 87, caused by the alpha decay of actinium-227.

Perey, however, continuously criticized Hulubei's work until she was credited as the sole discoverer of element 87.

Perey named the new isotope actinium-K ( now referred to as francium-223 ) and in 1946, she proposed the name catium for her newly discovered element, as she believed it to be the most electropositive cation of the elements.
