Julius Sachs, a noted German botanist (b. Breslau, 1832; d. Wiirzburg, 1897), was 

 a most careful observer of the ways in which plants live and work. He had a re- 

 markably clear and forceful style of writing and an unusual ability in making 

 illustrations. As investigator, writer, and teacher he organized the somewhat 

 disconnected discoveries of others and, adding his own discoveries, established 

 the science of plant physiology. His textbooks were unsurpassed in influence and 

 gave to many students their first general view of botany. He published many 

 important contributions to our knowledge of germination, the work of chlorophyll, 

 and other processes of food-making and food transportation
