HISTORY 2 7 



extraordinary industry is attested by the fact that his bibHography 

 runs to nearly eight hundred scientific papers. That even his work as 

 Assistant Librarian yielded a rich harvest is shown by his "Nomen- 

 clator Zoologicus," published in 1882 and containing a catalogue of 

 all the generic names employed by zoologists up to that time.^ 



Though undoubtedly the most learned entomologist of his genera- 

 tion, Scudder was far more. As Mayor says, "few men of science 

 have endeared themselves to those around them as did he, endowed 

 as he was with an innate quality of kindliness that, seemingly un- 

 known to him, graced his every word and act. One recalls his tall, 

 handsome form and the strong, interesting features so wonderfully 

 relieved by the happy soul that seemed ever ready to burst forth in a 

 bright flash of interest over any and all things of that manifold na- 

 ture to the observation of which his life had been devoted." 



Two other eminent entomologists followed Scudder as curators of 

 entomology. Alpheus Spring Packard (i 839-1 905) was engaged to 

 look after the collections in 1 864 and Phillip Reese Uhler(i 835-1 91 3) 

 from 1864 to 1867. Both men made notable contributions to our knowl- 

 edge of American insects and the former especially was interested in 

 every aspect of insect life. At Brown University Packard was later 

 professor of entomology and zoology, while Uhler became America's 

 leading authority on the Hemiptera and Homoptera, while acting as 

 librarian and later as provost of the Peabody Institute of Baltimore. 



Hermann August Hagen (1817-93), curator in the Museum of 

 Comparative Zoology from 1867 and also professor of entomology 

 from 1870-90, was born in Kdnigsberg, East Prussia. After graduat- 

 ing from the gymnasium, he studied medicine at the university of his 

 native city, where both his father and grandfather had been pro- 

 fessors. He was fortunate in having three remarkable teachers. Von 

 Baer, Rathke and Von Siebold. His thesis, presented for the degree 

 of Doctor of Medicine (i 840), was on the synonymy of the European 

 dragon flies. It is said that his attention had been attracted to the 

 Odonata " because by chance the first specimen he caught proved to 

 be an unidentified insect of that order." - After studying till 1843 ^^ 



' The motto of this work was taken from Pope's "Dunciad": 

 "... index-learning turns no student pale, 

 Yet holds the eel of science by the tail."
