In November 1969 He<strong>in</strong>z Gerischer was appo<strong>in</strong>ted to succeed Brill as chief<br />

<strong>in</strong>stitute director. He headed <strong>the</strong> Department of Physical Chemistry and <strong>in</strong>itiated<br />

research <strong>in</strong> <strong>the</strong> areas of electrochemistry, photo electrochemistry, and fast<br />

reactions. His department focused also on studies of solid surfaces under ultrahigh<br />

vacuum conditions and <strong>the</strong>ir <strong>in</strong>teraction with gases. Fur<strong>the</strong>r, exploit<strong>in</strong>g <strong>the</strong> low<br />

temperature technology already developed by von Laue at <strong>the</strong> <strong>in</strong>stitute, a<br />

research program on matrix isolation spectroscopy was started. Here <strong>the</strong> transition<br />

between atomic and metallic properties <strong>in</strong> clusters was <strong>in</strong>vestigated. When<br />

Gerischer was appo<strong>in</strong>ted, Jochen H. Block became Scientific Fellow of <strong>the</strong><br />

<strong>in</strong>stitute. He had <strong>been</strong> hired by Brill <strong>in</strong> 1966 and had built up his own department <strong>in</strong><br />

which k<strong>in</strong>etic processes on metal surfaces were studied us<strong>in</strong>g field electron and<br />

field ion microscopies. In 1974 a new build<strong>in</strong>g for electron microscopy was<br />

completed. This build<strong>in</strong>g was constructed <strong>in</strong> particular to isolate Ruska's ultrahigh<br />

resolution microscopes aga<strong>in</strong>st external vibrations.<br />
