movement in a very prominent way. She mothered generations of 

 young students who came to her husband's department for study, and 

 gave them an insight into home and social Hfe that made their stay 

 at Cornell very pleasant. 



Hermann August Hagen 



It would be difficult to overemphasize the authority in entomologi- 

 cal matters exercised by Hagen when he came to the United States. 

 In those early days he had around him at Cambridge a group of work- 

 ers of a distinctly high rank : E. A. Schwarz, who was brought over 

 by him from Germany soon after his own arrival ; H. G. Hubbard, 

 who graduated at Harvard in the class of 1873 ; G. H. Crotch, the 

 Englishman ; Baron Osten Sacken, and others. 



Hagen, in his " Bibliotheca Entomologica," had published in the 

 closing pages a very important analysis of the entomological writ- 

 ings of the world, and among other things had isolated from the mass 

 of titles those which referred to economic entomology ; and in doing 

 this he had gained a good knowledge of the economic work that had 

 been published. But he was not an economic entomologist. It is 

 true that he wrote a most interesting account of the medieval trials 

 by the courts of dangerous insects and that he wrote a paper sug- 

 gesting the practical use of the fungous diseases of insects. But no 

 one took him very seriously in economic entomology in those early 

 days. In fact Herbert Osborn has recorded the fact that he worked 

 one winter with Doctor Hagen and that the main thing Hagen tried 

 to impress upon him was that he should not be an economic entomolo- 

 gist — advice, of course, that he did not follow. On the other hand, 

 J, H. Comstock has stated that when he spent some time in Cam- 

 bridge alone with Hagen, he was given the first special course on 

 insect morphology given on this side of the Atlantic. Comstock goes 

 on to say: "And it was a wonderful course. Years afterwards when 

 I gave a course of lectures on insect morphology myself I would go 

 back for data to my notes on these lectures." Nowadays, when we 

 realize how much sound fundamental training means to the eco- 

 nomic entomologist, the influence of Hagen, through Comstock, must 

 not be forgotten. 



He was a tall, stout man, whose English was very bad. It was 

 most difficult to understand him. He visited Washington in the early 

 eighties ; and that was the first time I saw him. He would not speak 

 to Schwarz. I never learned why. There must have been some mis- 

 understanding between them before Schwarz left Cambridge with 

 Hubbard.
