About Luigi Rolla

Luigi Vittorio Maria Rolla was an Italian physical chemist. He worked in several universities before becoming a professor at the University of Florence. He worked on physical chemistry but became most well known after he made a claim to the discovery of the element with atomic number 61 which he thought to be stable, claimed to have extracted a pure sample, and gave the name Florentium. This was later found to be incorrect and the event known as the "Florentium fiasco" overshadowed his other works, including several military inventions.
