"Es ist ja ganz eineriei, wer es gejunden hat, die Hauptsache ist, daB es gejunden worden ist." This was said by Hermann Wilbrand, director of the department of opthalmology at the university hospital Hamburg-Eppendorf (1919-1923), when others claimed priority for the long searched for cortical visuell center, which he had discovered. Five years ago we tried in Wilsede an unusual experiment, bringing together for three long days and nights scientists and medical doctors to learn like students about each others work. The hope was that the participants in the workshop would discuss the whole problem of human leukemia, and coopera- tive programmes among the different specialized research groups and medical centers would be stimulated. Now five years later we feel that the experiment was a success. Coope- rative research programmes around the world were started and most of us understand more and more the Frederic Stohl- man question about the pratical application of our research and its benefit for the patient. The chairman have done a tremendous job organizing an up to date scientific programme for the third Wilsede meet- ing.I would like to thank all of them for a programme which includes all the important results and future aspects of human leukemia.

Gut ist eine Lehrart, wo man vom Bekannten zum Unbekannten fortschreitet; schon ist sie, wenn sie sokratisch ist, d.i. wenn sie dieselben Wahrheiten aus dem Kopf und Herzen des Zuhorers herausfragt. Bei der ersten werden dem Verstand seine Uberzeugungen in Form abgefordert, bei der zweiten sie ihm abgelockt.

Established clinicians and scientists as weil as students aga in tried the Wilsede experiment for three days and nights and learned from each other. In our fourth Wilsede meeting on "Modern Trends in Human Leukemia" we concentrated once again on questions re gar ding the practical application of research and its benefits to the patient. The main emphasis of leukemia research has changed since the first Wilsede meeting in 1973. Virology is no longer the sole interest.

mene Stil in jeglicher Kunst, daft er die spezijischen Schranken derselben zu entfernen weip, ohne doch ihre spezijischen Vorzuge mit aufzuhe- ben, und durch eine weise Benut- zung ihrer Eigentumlichkeit ihr einen mehr allgemeinen Charakter erteilt. Friedrich Schiller - Ober die as the- tische Erziehung des Menschen. In den Horen, 22. Brief (1795) We are glad that you have all come to this small village and I hope that you will feel at home here for the next few days. The special atmosphere of the surround- ings will probably have a good influence on our discussions, and you will perhaps remember this when you are back home again. It takes hard work to save this little piece of nature for man in our highly industrialized world, and we should all be grateful to the Verein Naturschutzpark e. V. (founded in 1909), Alfred Toepfer and his associates for their efforts. We intend to discuss modern trends in human leukemia in this workshop, but we should also take the opportunity to reflect on the trends of the past, which might still be modern.
