Extractions: From 1889-1890 he did his military service and then, after a period as a retail bookseller, he entered, in 1891, the University of Heidelberg . There, until he took his preliminary examination in 1893, he studied medicine, and was especially attracted by the work of the comparative anatomist there, Carl Gegenbaur. During the winter of 1893-1894 he studied at the University of Munich , where he became more closely acquainted with August Pauly - a fact of great importance to him. From the spring of 1894 to the end of 1908, he worked in the Zoological Institute at the . In 1895 he took his degree in zoology, botany, and physics (subjects to serve his anatomical studies), having worked under Theodor Boveri, Julius Sachs, and

Extractions: Nobel Prize for Physiology or Medicine in 1935 for his discovery of the effect now known as embryonic induction, the influence exercised by various parts of the embryo that directs the development of groups of cells into particular tissues and organs. Spemann's concept of induction was based upon a lifetime of research into the early development of the newt. His work showed that, in the earliest stages, the fate of the embryonic parts has not been determined: if a piece of presumptive skin tissue is excised and transplanted into an area of presumptive nervous tissue, it will form nervous tissue, not skin. These results illuminated not only normal processes of development but also the origin of congenital abnormalities. Spemann summarized his researches in Embryonic Development and Induction).

Extractions: Hans Spemann studied embyogenesis on the newt embryo by transplantation and by cutting off the circulation to certain tissues. One of his most famous experiments together with H. Mangold was the transplantation of the blastopol lip in a Triturus embryo, wich led to the formation of a second body axsis, like in siamese twins. On vertebrate eyes, he discovered the induction of different Anlagen, for example the induction of the lens from epidermal tissue. For the first time he tried to find causal relations between different events of the embryogenesis. He was the first zoologist to recieve the Nobel price. Document last modified March 10th, 1998 by

Extractions: Richard Seed Hans Spemann, a German embryologist, is one of the original pioneers of modern embryology , and one of only two embryologists to ever be awarded the Nobel Prize. His studies focused upon the differentiation of embryo cells during an organism's development. Spemann, born in Stuggart, Germany in 1869, attended the University of Heidelberg and the University of Munch before earning his Ph.D. in botany, zoology, and physics at the Zoological Institute of the University of Wurzberg in 1895. Spemann's fascination with embryology did not begin until after his college years, when during the winter of 1986 he read August Weismann's book The Germ Plasm: A Theory of Heredity as he sat isolated in a sanitarium, recovering from tuberculosis. In Spemann, ingeniously using a stand of hair as a noose, successfully split apart the

Extractions: In 1901, Curt Herbst wrote that he thought it possible "to establish the occurrence of formative stimuli which are exerted from one part of the embryo to another, and to demonstrate eventually the possiblity of a complete resolution of the entire ontogenesis into a sequence of such inductions." This prediction of inductive cascades was a bold statement, given that no sequence of events had yet been observed (1, 2). But that was soon to change. That same year, Hans Spemann (3) published "one of the most significant and seminal papers in the history of embryology" (4), his experimental analysis of lens formation in the frog. Spemann cauterized the prospective retina anlagen in the neurula stage Rana fusca Rana palustris (a related American frog) and got the opposite results: free lenses which were not connected to an eye. King's paper sent Spemann back to the laboratory where he did the identical experiment on different species of frog neurulae. He confirmed both his earlier results and Helen King's results (7). There was a component of induction that was species-specific. There appeared to be two ways to make a lens: induction or self-determination. Spemann put this result in the context of a model proposed the previous yearconcerning the operculum of amphibian tadpoles. When the limbs of amphibian tadpoles arise during metamorphosis, they emerge through an opening called the operculum. It had been thought that the limbs mechanically pushed through this barrier. However, when Herman Braus removed the forelimb rudiments, the operculum still openned at the appropriate time. Braus explained this phenomenon by introducing the engineering term "double assurance" into embryology (6). Spemann (8) maintained that double assurance also worked for amphibian lenses, and that while some frogs had only one mechanism of lens determination, most species were in between and had some self-differentiation but still required contact for optimum lens formation.

Extractions: Spemann, Hans Hans Spemann est né le 27 juin 1869, à Stuttgart. Il était le fils l'aîné de l'éditeur, Wilhelm Spemann. De 1878 jusqu'à 1888 il est allé à l'Ecole Eberhard-Ludwig à Stuttgart et quand il a laissé(quitté) l'école en 1888 il a dépensé(passé) une année dans l'affaire de publication de son père. De 1889-1890 il a fait son service militaire et ensuite, après une période comme un libraire au détail, il est entré, en 1891, l'Université de Heidelberg. Là, avant qu'il n'ait pris son examen préliminaire en 1893, il a étudié la médecine et a été particulièrement attiré par le travail de l'anatomiste comparatif là, Carl Gegenbaur. Pendant l'hiver de 1893-1894 il a étudié à l'Université de Munich, où il lui est devenu plus étroitement(de près) mis au courant août Pauly - un fait très important. Du printemps de 1894 à la fin de 1908, il a travaillé dans l'Institut Zoologique à l'Université de Würzburg. En 1895 il a pris son degré dans la zoologie, la botanique et la physique (des sujets pour servir ses études anatomiques), ayant travaillé sous Theodor Boveri, Julius Sachs et Wilhelm RoNtgen, tout de ce qui avait l'influence la plus grande sur son développement scientifique. En 1898 il a qualifié comme un conférencier dans la zoologie à l'Université de Würzburg et en 1908 on lui a demandé de devenir le Professeur de Zoologie et l'Anatomie Comparative à Rostock et en 1914 il est devenu le Directeur d'Associé du Kaiser Wilhelm l'Institut de Biologie à Berlin-Dahlem. En 1919 il a été nommé le Professeur de Zoologie à l'Université de Freiburg-im-Breisgau, dans la succession à Hans Doflein, un poste qu'il s'est tenu avant qu'il n'ait mis à la retraite et soit devenu le Professeur honoraire en 1935.
