private schools and received a broad general education, including 

 much training in Latin and German. When young Uhler was 

 about ten years old his father bought a farm near Reisterstown, 

 where the family often spent vacations. Here the boy began col- 

 lecting insects, and was encouraged by the we^-known Lepidop- 

 terist, the Rev. J. G. Morris and J. F. Wild, a German amateur 

 Entomologist residing in Baltimore. 



When of age his father placed him in his establishment, but the 

 young man was so interested in collecting and studying geological, 

 botanical, and zoological material that most of his time was spent 

 in this way. He soon obtained a local reputation as an all around 

 naturalist. Although in later life he specialized in Hemiptera, 

 he never lost interest in the broader problems of natural history 

 and science in general, and was always quick to perceive the ap- 

 plication of these broader studies to his special work on Hemiptera. 



In 1864 he was appointed by Prof. Louis Agassiz to take charge 

 of the collection of insects in the Museum of Comparative Zoology. 

 He also had charge of the library. Here he remained three years, 

 during which time the Museum received large accessions of mate- 

 rial. He made collecting trips for the Museum, to Maryland and 

 to Haiti, West Indies. In 1867 he returned to Baltimore. 



Before Dr. Uhler went to Cambridge he had been, for a short 

 time, assistant librarian to the Rev. J. G. Morris, at the Peabody 

 Institute. Upon his return he was again appointed, and in 1870 

 became librarian. Upon the death of the Provost of the Insti- 

 tute (Dr. N. H. Morrison) in 1880, he succeeded to that position, 

 which he held until failing health compelled him to ask for retire- 

 ment in 1911. He perfected the cataloguing system at the 

 Institute. 



His early work at the Peabody Institute allowed him sufficient 

 leisure to study and publish on the Hemiptera. For many years 

 he was practically the only authority on Hemiptera. The Hemip- 

 tera from the various government expeditions were sent him for 

 study, and many private collectors gave him material. In 1875 

 he spent two weeks on the plains and mountains of eastern Col- 

 orado. Here he collected insects of all orders, and in addition to 

 reporting on the Hemiptera, he made a report, with notes of habits 

 and occurrence, on all other insects. About 1888, in company of 

 his wife he visited Europe, purchasing books for the Peabody In- 

 stitute and examining the Hemiptera in European collections. 

 His entomological correspondence was very extensive, and in the 

 course of years he had to determine many thousands of Hem- 

 iptera for his numerous friends and correspondents. But he at- 

 tended to his arduous and often thankless work with the greatest 

 patience and thoroughness.
