PEEFACffO THE FIRST EDITION 



THIS BIOGRAPHICAL EJECTORY OF AMERICAN MEN OF SCIENCE 

 was begun as a manusci reference list for the Carnegie Institution of Washing- 

 ton, which made an appropria i of 351,000 toward the clerical and office expenses. It 



is hoped that the publication 

 America. There is here given 



11 be a contribution to the organization of science in 

 the first time a fairly complete survey of the scientific 



activity of a country at a giv period. As a reference book for the field it covers, it 

 may be even more useful in i iemic circles than Minerva or Who^s Who in America. 

 But the chief service it shouliender is to make men of science acquainted with one 

 another and with one anothe:work. There scarcey exlists among scientific men the 

 recognition of common interes.nd the spirit of cooperation which would help to give 

 science the place it should hi in the community. It is fully as important for the 

 nation as for men of science it scientific work should be adequately recognized and 

 supported. We are conseque y in the fortunate position of knowing that whatever 

 we do to promote our own inf sts is at the same time a service to the community and 

 to the world. 



There are included in the rectory the records of more than four thousand men of 

 science, and it is believed th 

 America who have carried or;search work in the natural and exact sciences. Some 



are admitted who are suppose 

 work, or by the preparation o. 



o have advanced science by teaching, by administrative 

 ;xt-books and compilations. There are also some whose 

 work has been chiefly in engii ring, medicine or other applied sciences, and a few whose 

 work is in education, econors or other subjects not commonly included under the 

 exact and natural sciences, it the book does not profess to cover these fields. The 

 names are included because tr are supposed to represent work that has contributed to 

 the advancement of pure scie] ; the term being used in the narrower sense or because 

 they are found in the membe ip lists of certain national societies. *****

(9) Chief subjects of research, )se accomplished being separated by a dash from those in progress. 



A star is prefixed to th( ubject of research in the case of about a thousand of the 

 biographical notes. These a the thousand students of the natural and exact sciences in 

 the United States whose wc is supposed to be the most important. In each of the 

 twelve principal sciences thdames were arranged in the order of merit by ten leading 

 students of the science. Th average positions and the probable errors were then calcu-
