 Later when Prof. John B. Smith, of New Brunswick, N, J., was look- 

 ing for an assistant, both Mr. Doll and Mr. Engelhardt recommended 

 Mr. Grossbeck for the position, which he secured. Thus he became 

 associated in the work on New Jersey mosquitoes in 1903, and 

 naturally from the environmemt became interested in Lepidoptera and 

 particularly in the family Gcomctridae. This last choice was no doubt 

 brought about by the presence in New Brunswick of the Hulst col- 

 lection. From what he learned in the Agricultural Experiment Sta- 

 tion, and as a member of a correspondence school, he progressed 

 rapidly and soon commenced publishing scientific papers. 



Prof. Smith told me on several occasions that one of his best dis- 

 cov^eries was Grossbeck. He would work both during office hours 

 and out of them, as diligently and carefully as possible, his desire 

 being to get the work well done, and usually it was so very well 

 done that all were pleased. There are, and have been in the past, a 

 great many clever entomologists, but it isn't so often that they com- 

 bine cleverness and artistic neatness as well. This he displayed in 

 his arrangement of collections to a marked degree. His ability to 

 make detailed drawings of insects was of great service to Prof. Smith, 

 and also to himself in his work on the Geometridae as shown by the 

 figures illustrating many of the papers mentioned in the bibliography. 

 In this direction he was also always ready to assist his friends, and 

 several are indebted to him for sketches to illustrate their papers. 



On February 20, 1911, he became officially associated with the 

 American Museum of Natural History, to which institution be gave 

 his collection of insects, including a considerable number of types of 

 Geometrid moths. In return the Trustees of the Museum elected him 

 a patron. In 191 1 he moved to Staten Island and in 1912 built a 

 shingle covered bungalow in the picturesque Clove Valley, which 

 he occupied with his wife and two infant sons. 



While employed in New Brunswick Mr. Grossbeck was a member 

 of the Newark Entomological Society, and served as its secretary for 

 a number of years. At the time of his death he was librarian of the 

 New York Entomological Society, and a member of the Staten Island 

 Association of Arts and Sciences. 



It has been a simple task to compile a bibliography of the writings 

 of my friend, for like everything else that he had, his papers were in
