Jean Louis Rudolphe Agassiz was born in Switzerland, in 

 1807, and died at Cambridge, Massachusetts, in 1873. He was 

 especially noted for his work in geology and ichthyology (the 

 science of fishes). 



Agassiz came to the United States in 1846 on a scientific expe- 

 dition and took up his residence here, becoming Professor of 

 Zoology and Geology at Harvard, and Curator of the Museum of 

 Comparative Zoology at Cambridge. He explored the Lower 

 Amazon in 1865-66. In 1871-72 he accompanied the Hassler 

 expedition to the South Atlantic and Pacific. 



Few have done more than Agassiz to popularize science, and 

 few teachers have trained so many young and rising naturalists.
