an extreme modesty and a complete absence of private 

 interest for all science outside his own, Pander 

 remained outside the official world of science. His 

 life was so devoid of scientific honors that even 

 after death he was forgotten. Not one scientific 

 organization kept his obituary or a list of his 

 numerous works .... Many of the results of his 

 scientific investigations were published in the work 

 of others. 5 



Pander died in 1865. 



Concerning Pander's working conditions in Wurzburg, 

 Baer reported the following: Dollinger gave Pander the pro- 

 cedures of investigation which he had worked out for early 

 chicken embryos, namely the method of separating the blasto- 

 derm from the yolk under water. This method had been 

 previously employed, apparently, by Malpighi and Wolff, but 

 they did not give a description of it. For this reason, 

 it was not known to Haller and Ham, whose achievements 

 therefore were consequently insignificant. Of Ham's work 

 Baer wrote, for example, that "Ham is significantly later 

 than Wolff, even later than Pander. He has offered us 

 investigations of the chick embryo from which it is not 

 possible to know more than that the embryo gets larger and 

 larger. "6 "And thus," Baer continued, 



Pander could use Dollinger' s experiments and more 

 expedient methods. But in order to obtain true 

 impressions about this progress (Baer means the 

 most important question in chicken embryology— the 

 formation of the intestines and peritoneal cavity) 

 it is necessary to start from the beginning and 

 follow all the stages of the chick successively. 

 This was done by nobody else but Pander. 7 



Already on July 10, 1816 Baer wrote to his friend Dietmar: 8 



Because you have shown such interest in Pander's 

 work, I cannot postpone telling you about it,
