Charles Mohr. 

 1824-1901. 



Carl Theodor Mohr or Charles Mohr, as he preferred to be 

 known, will be remembered for his many important contribu- 

 tions to natural science. He was born at Esslingen on the 

 Neckar, in Wurttemberg, Germany, December 28, 1824. At 

 an early age he took a deep interest in scientific studies, and 

 embraced every opportunity for extending his knowledge. Soon 

 after his father's death, young Mohr devoted his hours after 

 school to practical work in a chemical factory at Denkendorf, 

 in which his father had been interested. His taste for the 

 sciences was further developed by reading, and his love of 

 nature was awakened by companionship with his great-uncle, a 

 pensioned government forester, whom he frequently joined in 

 his excursions into neighboring forests. 



At the age of eighteen Mohr entered the Polytechnic School 

 at Stuttgart, where he became interested in botan}^ Here he 

 formed the acquaintance of the botanists Hohenacker and Kapp- 

 ler. In 1845 he accompanied Kappler on one of his botanical 

 explorations to Dutch Guiana. Returning to Europe after a 

 protracted illness. Dr. Mohr became chemist for a manufacturing 

 firm in Brunn, Austria. But the political disturbances of 1848 

 impelled him to leave Europe for the United States, where the 

 remainder of his life, extending over more than fift}- years, was 

 passed. 



Dr. Mohr brought to America the same enthusiasm that had 

 characterized his work in Europe, and that ever after consti- 

 tuted one of the marked traits of his character. After a short 

 residence in Cincinnati in the employ of a manufacturing chem- 

 ist, in March, 1849, he joined a party of young men on their 

 way to the newly discovered gold diggings in California. 

 During his long journey across the Plains and Rocky Moun- 

 tains he again became deeply interested in botanical research, 

 although his efforts were attended with singular misfortune. 

 He was obliged to abandon one valuable collection of plants
