MEMORIAL OF ORVILLE A. DERBY 

 BY JOHN C. BEANNEE 



Oivillc Adelbert Derby was born at Kelloggsville, New York. July 23, 

 1851; and died by his own hand at Eio de Janeiro, Brazil, November 27, 

 1915. He was the third son of John C. Derby and Malvina A. Lindsay 

 Derby, and was reared on a farm near Kelloggsville, in Cayuga County, 

 in the "Finger Lakes" region of New York State, about 16 miles south- 

 east of Auburn. 



Derby entered Cornell University in 1860, and while yet a freshman he 

 became so interested in geology and was such a promising student that 

 lie was selected by Prof. Charles Fred Hartt, then professor of geology 

 at Cornell, to accompany him on a trip to Brazil in the summer of 1'870. 

 An incident showing a characteristic trait of the man had something to 

 do with his selection for assistant on that trip and for his subsequent 

 promotions. Professor Hartt had to leave the university for an absence 

 of two weeks. He was a bit uncertain as to what could be done during 

 his absence with this very new student of his. At a venture he gave him 

 Hall's volume on the fossil bryozoa of New York — a work that Mould 

 certainly have cooled the unguided ardor of most beginners. When Hartt 

 came back at the end of two weeks Derby was patiently pegging away on 

 the bryozoa. Hartt' s heart warmed to a student who had the grit to stick 

 to his uninspiring work, and shortly thereafter the opportunity to visit 

 Brazil was given him. Derby gladly accepted the invitation, and in doing 

 so he determined both his career and the whole course of his life. 



On his first voyage to South America he went to Pernambuco and made 

 the first considerable collections of fossils ever made at Maria Parinha.
