"Es ist ja ganz einerlei, wer es gefunden hat, dlie Hauptsache ist, daß es gefunden 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 cooperative 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. Cooperative research programmes around the world were started and most ofus understand more and more the Frederic Stohlman 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 meeting. I would like to thank all of them for a programme which includes all the important results and future aspects of human leukemia.

Personal and scientific discussion in Wilsede, June 1978

Highly qualified scientists did not only prepare themselves for a talk. but also for posters to give us a chance for more personal discussions about the clinical and research fields we are interested in. I hope that these possibilities of individual discussions will help understanding the different fIelds impor tant for human leukemia. as an example for human caneer The special Wilsede atmosphere probably will have again a good influence on our discussions and perhaps you will take home some of this spirit and remember it sometimes. Than we should be grateful to the Verein Naturschutzpark e.V. and especially to Alfred Toepfer and his associates for their idealistic efforts to save this little piece of nature for man.
