Darwin, charles 



Darwin's name is known to every school child, at least from the secondary 

 school level upwards. He was born in 1809 and died in 1882. Darwin is re- 

 nowned for his Theory of Natural Selection by means of which he attempts 

 to explain how evolution operates. It may be safely said that his work did more 

 to stimulate scientific endeavors along modern research lines than any pre- 

 ceding book. In addition to his work on Natural Selection, Charles Darwin 

 did notable works on animals and plants under domestication, the descent of 

 man, fertilization in the orchids, and earthworms, to mention the most im- 

 portant.

Hippocrates 

 The most famous of the early Greek physicians, Hippocrates lived from 460- 

 377 B. c, although there is some uncertainty' about these exact dates. Some of 

 our present medical knowledge had its foundation in the work of Hippocrates 

 and his followers. They had a fairly good idea of the bones and muscles of 

 the body, the cavities of the heart and the general structure of the eye and the 

 ear. When one considers that dissections of the human body were not per- 

 formed after death and that chemistry and chemical experimentation on ani- 

 mals was almost unknown, one must be impressed with the amount of accurate 

 information that the early Greeks were able to acquire.
