Abstract
With his theoretical work Walter Greiner, our mentor, pioneered super heavy element research and motivated us young scientists. He actively shaped the profile of GSI. We are happy that still during his lifetime we could prove some of his predictions: Fusion with magic nuclei paving the way to super heavy elements and the proof of the prediction of the nuclear species existing only by shell stabilization, super heavy elements. With the discovery of oganesson, Z=118, the heaviest element known today, we have come to the end of this era. New experimental developments will be discussed.

With element 118 the synthesis of super heavy elements with actinide targets and 48Ca beams, the era of synthesis of super heavy elements with doubly magic nuclei, as theoretically substantiated by Walter Greiner has come to its end
Summary
Super-heavy element research was pioneered and strongly supported by Walter Greiner. In his early calculations he worked on the prediction of super heavy elements: atomic nuclei existing only by shell stabilisation in the sea of liquid-drop instability [1] and heavyelement production in reactions with the doubly magic nuclei, 208Pb and 48Ca [2,3]. Main issues were the specifications for the accelerator to accelerate all ions of all elements of the periodic table and the production of new chemical elements and isotopes including Super Heavy Elements, SHE: The uranium beam as a rich source for new isotopes at the GSI fragment separator, and the new super heavy elements at SHIP. Both the basis for success of GSI
