All knew and honored the great Baer; many remembered his 

 fellow and direct predecessor, H. C, Pander. It is important 

 to remember the name of that first embryologist of the nine- 

 teenth century, L. Tredern, who links Wolff and Baer in the 

 history of Russian and world embryology. As the work of Wolff 

 was apparently a model for Tredern and a stimulus to his 

 continuation of research from the point at which Wolff had 

 stopped, so Tredern' s humble work played a similar role as 

 stimulus and model for Baer, though Baer surpassed that model 

 significantly.
