It is always difficult to write introductory articles of this kind. The reason is clear: is the personality to be introduced reflected on paper well enough, is his identity explained properly? It depends sometimes on the ability of the writer, and sometimes on the power of the words chosen. It becomes even more difficult when the person in concern is a man of sciencewith as many abilities as Prof. Hagen Lichtenberg. I have known Prof. Lichtenberg of Bremen University since the 1970's. When I was a student in the department of economics of BremenUniversity, I used to see Prof. Lichtenberg quite often despite the fact that our departments were different. We used to greet each other with great friendliness and talk briefly if he wasn't in a hurry. Besides, I had the opportunity to attend many international conferences and seminars in which he participated. His papers and speeches on "Social policy, labour law, labour market and the free movement of workers in the European Community" were read and listened to carefully by many Turkish students including myself.
