Abstract
DR. MAX . HARTMANN, director of the Kaiser Wilhelm Ins Kir Biologie, spent his seventieth birthday 9th July 7 on his small farm in the Allgan. On Vfcf tn§ rfuj tanding personalities among German biolots of his generation, he can look back upon a fine record of original research, particularly in the field of sexuality and fertilization in Protozoa and Algae. His investigations of ‘relative sexuality’ have led to very important biochemical studies of the substances produced and released by gametes and essential for fertilization in Algae, echinoderms, molluscs and fishes (cf. iLord Rothschild's article in Nature of June 1, p. 720). Realizing the great opportunities opened up by the transition from the morphological to the experimental approach to biological problems, he has been singularly successful in guiding a large number of young workers to new and fruitful fields of research, inspiring them with his own enthusiasm for every great discovery made, whether in protozoology, cytology, genetics, experi mental embryology or physiology. His capacity for critically sifting and clarifying the progress made is well reflected in his “Allgemeine Biologie”, of which the third edition is now in the press. Dr. Hartmann was aijaarless and outspoken critic of Nazism.
