Being more than 19 years head of the Eye Clinic, Charité-Campus Benjamin Franklin, Prof. Dr. Michael Foerster (Figure 1) is a leading expert in the field of eye tumors in the ocular fundus. These tumors are the result of an extremely malicious disease, which not only menace the ability to see, but also but a patient in mortal danger. Patients with eye tumors are being treated with proton beams since June 1998 by the Universitätsklinikum Benjamin Franklin of the Freie Universität Berlin (now: Charité, Universitätsmedizin Berlin, Campus Benjamin Franklin) together with the Hahn-Meitner-Institut (now: Helmholtz-Zentrum Berlin für Materialien und Energie) in Berlin.
