"Glory to the science of embryology!" So Johannes Holtfreter closed his letter to this editor when he granted permission to publish his article in this volume. And glory there is: glory in the phenomenon of animals developing their complex morphologies from fertilized eggs, and glory in the efforts of a relatively small group of scientists to understand these wonderful events. Embryology is unique among the biological disciplines, for it denies the hegemony of the adult and sees value (indeed, more value) in the stages that lead up to the fully developed organism. It seeks the origin, and not merely the maintenance, of the body. And if embryology is the study of the embryo as seen over time, the history of embryology is a second-order derivative, seeing how the study of embryos changes over time. As Jane Oppenheimer pointed out, "Sci ence, like life itself, indeed like history, itself, is a historical phenomenon. It can build itself only out of its past. " Thus, there are several ways in which embryology and the history of embryology are similar. Each takes a current stage of a developing entity and seeks to explain the paths that brought it to its present condition. Indeed, embryology used to be called Entwicklungsgeschichte, the developmental history of the organism. Both embryology and its history interpret the interplay between internal factors and external agents in the causation of new processes and events.

Excerpt from Text-Book of the Embryology of Man and Mammals The history of the development of the individual, or Ontogeny (embryology), is the science of the growth of an organism 5 it de scribes the morphological changes which an organism passes through from its origin in the ovum up to its complete maturity, and presents these in their natural connection. We can regard the fertilisation of the egg-cell as the beginning of the process of development for Vertebrates, as it also is for all the rest of the higher animals. In giving an account of the changes of the egg-cell, which begin with fertilisation, one may choose between two different methods. According to one method a particular organism is made the basis of the account, and one describes the changes which its germ under goes from the moment of fertilisation onward, from hour to hour, and from day to day. It is in this way that the embryology of the Chick has been worked out by C. E. Von baer in his classical paper, and by foster and balfour in their Elements of Embryology. This method has the advantage that the reader acquires a View of the total condition of an organism in the separate stages of its development. A book of that kind is especially suitable for such persons as desire to acquaint themselves, by their own observation, with the embryology Of a single animal, as, for example, the Chick, by repeating the investigations of others. It is, on the contrary, less adapted to those who wish to acquire a connected view of the development of the separate organs, as the eye, the heart, the brain, etc. For the formation of these will of course be treated of at different places in describing younger and Older embryos. In order to procure a general survey of the course of development of an organ, the reader must consult various places in the text-book, and collect for himself what relates to the subject.

Excerpt from The Popular Science Monthly, Vol. 69: July to December, 1906 Embryology is so vast and varied that it offers problems adapted, I might almost say, to every size of mind, and persons of moderate capacity, as well as those of the highest gifts of genius, can find adequate opportunity to gratify successfully in the field of embryology any demon of research which may possess them. Let us first consider some of the conditions upon which the progress of embryological science has depended. Of course the first and allessential thing is the amount and quality of human ability which has gone into it. This is true of every science, as goes without saying. It may, however, be interesting to pause a moment, since contemporary events are directing so much of the interest of the world towards Russia, in order to point out that modern scientific embryology had its birth in that country, for the first step was the publication of the articles by C. F. Wolff on the 'Theory of Generation and the Development of the Intestine in the Chick'; and the second and more important step was the publication of the great work of Carl Ernst von Baer, which may be said without exaggeration to have created by itself a new science. Von Baer's treatise on the 'Entwickelungsgeschichte der Thiere' is one of the greatest works in the whole history of biological science, and established the author's reputation as a genius of research. By the aid of improved methods a tyro in embryology may now verify von Baer's discoveries, but there has been no one since von Baer, who could have approached with his scientific resources the magnitude of his achievement. Let us then honor his memory. Although Wolff and von Baer, both, were Russian subjects, they were of German descent, and we find indeed that throughout the greater part of the last century the advance of embryology was due chiefly to German investigations. How recent this knowledge is we are apt to forget. From 1800 to 1840 the seminal animalcules were universally regarded as parasites. The fact that they are normal products of the testis and the true male sexual elements was first discovered in 1841 by the Swiss anatomist von Kolliker, who was a leader in microscopical research for sixty-five years, and whose death occurred last year. Of Kolliker it may be asserted safely that he knew more by direct personal observation of the microscopical structure of animals than any one else who has ever lived. He was much honored in Europe. The last time I met him was at the International Zoological Congress at Berne, in 1894. It was most impressive to see all the members of the congress spontaneously rise to their feet when the handsome old man unexpectedly entered the meeting. The fact that the spermatozoon enters the ovum and produces the so-called male pronucleus, the union of which with the female pronucleus completes the act of fertilization, was finally demonstrated only in 1875 by Oscar Hertwig.
