These early studies, brought out at a time when cellular biology 

 was in the period of anticipatory speculation, exerted wide influence 

 in directing attention to the study of the laws of normal develop- 

 ment from the standpoint of the cell, and they were followed later 

 by equally stimulating studies in experimental embryology and 

 experimental cytology which were carried out with special reference 

 to the problems of mosaic development, prelocalization, and differ- 

 entiation in the egg. During the last decade his interests have 

 also turned to the mechanism of the cell and here again, his 

 researches on the structure of protoplasm, on the history of 

 centrosome, aster and karyokinetic figure, and on the chromo- 

 somes with special reference to the questions of heredity and sex, 

 have had a wonderfully stimulating effect on biological research 

 throughout the world. Many of these studies, too numerous to 

 be listed here, were unified and worked up into harmonious relations 

 with the modern aspects of the fundamental problems of biology 

 in his book on The Cell in Development and Inheritance, which, 

 through clearness of style and masterly critical analysis, has been 

 one of the most widely read of modern technical scientific works, 

 and is the one by which he is best known. 



Professor Wilson's scientific attainments have been widely 

 recognized in academic circles and by scientific societies. He is a 

 member of the National Academy ; a Fellow of all the general 

 zoological societies of this country ; of the Royal Microscopical 

 Society of England, of the Accademia dei Lincei of Rome and of 

 other societies. He received the LL.D. degree from Yale Uni- 

 versity and from the University of Chicago in 1901, and from Johns 

 Hopkins University in 1902.
