SECOND EDITION, NOVEMBER, 1910 



AMERICAN MEN OF SCIENCE 



A BIOGRAPHICAL DIRECTORY 

 EDITED BY J. HcKEEN CATTELL 



A Biographical directory requires revision if it is to maintain its usefulness. Nearly a third of the names in the 

 present edition are new, and the sketches which appeared in the first division have in nearly every ease been revised. The 

 amount of work required to prepare the revision has been as great as that given to the first edition. There has been no 

 change in the general plan of the work. Greater strictness has been observed in confining its scope to the natural and 

 'he first edition have been omitted. Efforts have been exerted to 



make the book as complete and accurate as possible. There are of course omissions, if only I 



reply even to repeated requests for the information needed. The thousand leading men of science have been again selected 

 by the methods that were used before, and stars hare been added to the subjects of research in the ease of 869 new men who 

 have obtained places on the list. The editor's object in selecting this group of scientific men has been to make a study of 

 the conditions on which scientific research depends and so far as may be to improve these conditions. There are printed in 



than 5500 sketches.
