This article describes the experiments that were performed during the first decade of the operation of UNILAC, GSI-Darmstadt, at the recoil separator SHIP and the on-line mass separator. The measurements resulted in the discovery of the first radioactive ground state proton emitters, [sup151]Lu and [sup147]Tm
