Ausenium (atomic symbol Ao) and Hesperium (atomic symbol Es) were the names initially assigned to the transuranic elements with atomic numbers 93 and 94, respectively. The discovery of the elements, now discredited, was made by Enrico Fermi and a team of scientists at the University of Rome in 1934.
