Answer:
Ida Tacke was on the German team that thought they'd discovered the element technetium back in 1925. Their results could not be reproduced.

It fell to Italians Carlo Perrier and Emilio Segrè, working at the University of Palermo in Sicily in 1937 to finally isolate and identify the synthetic element. It is of note that this metal was removed and concentrated from a material given to the two scientists by Ernest O. Lawrence. It was from irradiated shielding from a cyclotron that technetium was first recovered.
