Abstract: In the present paper, we present measurements that led to the discovery of two-proton radioactivity. After the first observation of this decay mode for <superscript>45</superscript>Fe, new measurements evidenced this decay mode also for <superscript>54</superscript>Zn and most likely <superscript>48</superscript>Ni. A new detector based on the time-projection chamber principle allowed now to visualize the two protons directly. [ABSTRACT FROM AUTHOR]
