The history of molecular biology in Germany is closely linked to the Institute of Genetics in Cologne, the first molecular biological Institute at a German university. Founded in 1959 by the ?©migr?© physicist and future Nobel laureate Max Delbr??ck, the Institute was the first in Germany to implement less hierarchical American organizational structures and research habits. The Institute had already gained an excellent international scientific reputation by the beginning of the 1960s. This volume comprises the recollections of scientists pertaining to the Institute s research, organization and other specificities. Articles by historians of science analyze the historical background and international framework of the Institute's foundations and genetic research. In addition, the scientists discuss contemporary questions of science policy with regard to teaching and the impact of the internal structures of scientific institutions on the quality of research.
