SECOND EDITION, NOVEMBER, 1910 
AMERICAN MEN OF SCIENCE 
A BIOGRAPHICAL DIRECTORY 
EDITED BY J. MicKEEN 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 case 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 
exact sciences, and for this reason a few names included in the 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 because some men will not 
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 have been added to the subjects of research in the case of 269 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 vmprove these conditions. There are printed in 
an appendiz the two statistical studies that have been made.—From the Preface to the Second Edition. 
The second edition of the Directory extends to more than 600 pages and contains more than 5500 sketches 
Is is well printed on all rag paper and bound in buckram with leather label. Although the work has been 
inoreased in size by more than 50 per cent., it issold at the same price as the first edition.
