Biographical Notice of Professor Joseph Henry. By Fairman Rogers. 

 {Read before the American Philosophical Society, February 20, 1880.) 



The admirable memoir of Prof. Joseph Henry, prepared by Mr. William 

 B. Taylor, and read before the Philosophical Society of Washington, 

 October 26, 1878, is so exhaustive both as to his scientific labors and the 

 incidents of his life that little can be added to it until at some future time 

 a biographer will undertake the preparation of a more voluminous life and 

 letters. 



As to his scientific career, the memoir deals principally with his earlier 

 work as being more directly personal, and the results of his own manipu- 

 lation and experiment, while his later days were devoted to the direction 

 and coordination of the work of others. 



Regret has frequently been expressed by the scientific friends of Prof. 

 Henry, that his acceptance of the Secretaryship of the Smithsonian, and 

 his devotion to the interests of that Institution had withdrawn him from 

 those lines of original research, in which he shone so conspicuously, and 

 while these regrets are perhaps well founded, it is a question whether he 

 could possibly have been of more value to science under any circumstances 

 other than those in which this later part of his life was passed. 



In his position his infiuenoe upon American Science was great and 

 varied. He was a constant and shining example before the eyes of the 

 younger scientific men of an unselfish devotion to the interests of science 

 for itself, and not for self aggrandizement. Honest in the widest and 

 deepest sense of the word, he never permitted expediency, self-interest or 

 passion to interfere with the search for truth, and his clear and simple ex- 

 pressions on such subjects put it out of the power of those who consulted 

 him to do otherwise than follow the example which he set them.
