CORRESPONDENCE Hahn's Nobel Was Well Deserved

CORRESPONDENCE It is true that we are suffering from bud Hahn's Nobel was well deserved get cuts more than non-university research institutions. The well-being of the universi SIR - I read with interest the repore on the for chemistry to Hahn (or perhaps to Hahn ties is evidently not high on our politicians' internal debates in the Nobel committee and his collaborator Strassmann). Whether priority list. For example, the decision not to that preceded the award of the Nobel prize Meitner (perhaps with Frisch, that excellent house the Institute for Molecular Pharma to Otto Hahn in 1945. I am one of the few theoretician) should have been given the cology in existing buildings close to the surviving witnesses of Hahn's studies lead prize for physics for first confirming the the medical school of the Free University but, ing to the discovery of uranium fission, oretical correctness of Hahn's interpretation instead, to erect a new building on the site although I knew nothing at the time about of his result is an open question. I think of a non-university institution, is just anoth the details. Hahn himself would gladly have accepted er instance of the political myopia that fails As a young theoretical physicist, I worked that. But the discovery itself was clearly to see how the quality of university research for six months in 1936 with Lise Meitner in Hahn's. will be reflected in the qualifications of the her section of the Kaiser-Wilhelm-Institut Carl Friedrich v. Weizsacker next generation of researchers. Neverthe fiir Chemic in Berlin-Dahlem, of which Maximilianstrasse 14c, less, I am happy to report that more than Hahn was the director. I then went to the D-82319 Starnberg, 700 full professors, about 3,000 scientists, Kaiser-Wilhelm-lnstitut fiir Physik, also in Germany and 49,000 students are still working hard Berlin-Dahlem, five minutes' walk away. In and successfully at the Free University of the last week of 1938, Hahn telephoned and SIR - Crawford et al. 1 deserve credit for Berlin. So we are suffering because of short asked me: "Can you imagine a radium their Commentary article in which they shed sighted politics but wreaths are premature. which in every chemical separation does not more light on the circumstances leading Klaus Roth go with radium but with barium?"

The members of his institute, I soon learned that of their alleged work on the atomic bomb in article was apparently based on a distorted Hahn and Meitner had discussed the prob Germany.
