SCIENCE

on March 1, 1849, and died at Los Altos, Cal., 

 on June 4, 1911. 



The fact that the writer has been intimately 

 associated with Professor Dudley since the 

 day he entered the freshman class at Cornell 

 University, in September, 1870, will perhaps 

 excuse the personal element in this little 

 sketch. 



The word " instructor " as a technical term, 

 describing a minor assistant to a professor, 

 had just then been invented, and the present 

 writer had just been appointed " instructor in 

 botany " under Professor Albert N. Prentiss. 



One day, Professor Henry T. Eddy, now of 

 Minnesota, brought to me a tall, well-built, 

 handsome and refined young man, older and 

 more mature than most freshmen, and with 

 more serious and definite purposes. Young 

 Dudley had an intense delight in out-door 

 things and especially in flowers and birds. 

 He wanted to be a botanist, and had turned 

 from old Tale, to which as a descendant of 

 Chittendens, Griswolds and Dudleys he would 

 naturally have gone, to new Cornell, because 

 Cornell offered special advantages in science, 

 and because at Cornell a good man could, if 

 need be, pay his own way. For the rest of my 

 stay at Cornell, Dudley was my room-mate, 

 living in a cottage on the hill, built by stu- 

 dents and termed " University Grove." In 

 this cottage was established the boarding-club, 

 known later and appropriately as " The Strug- 

 gle for Existence," and in later and more 

 economical times as the " Strug." Por a time, 

 Dudley paid his way by rising at four o'clock 

 to milk cows at the farm. Later he was 

 made botanical collector, and this congenial 

 "work he kept up until he became my suc- 

 cessor as instructor in botany. In college 

 Dudley was a member of the Delta Upsilon 

 fraternity, and took an active part in holding 

 this society to the high ideals (dikaia upoth- 

 eke) on which it was originally based. He 

 was also a charter member in the honorary 

 ■scientific society of Sigma Xi (spoudon 

 xunones). 



In 1871 I went with him to his home at 

 North GuiKord, and I remember that his 

 practical father said to me: 



There eoines Willie across the fields with his 

 hands full of flowers, just as he used to. I 

 wonder if there is any way he can make a living 

 by it. 



Dudley graduated from Cornell in 1874, 

 with the degree of B.S. In 1876, he received 

 the degree of M.S., after which he spent some 

 time in botanical study in Strassburg and 

 Berlin. Prom 1872 to 1876 he was instructor 

 in botany at Cornell, his eminent knowledge 

 of the eastern flora overbalancing the fact 

 that at first he had not yet received a degree. 

 From 1876 to 1892 he was assistant professor 

 of botany at Cornell, with a year's absence in k 

 1880, in which he served as acting professor 

 of biology in the University of Indiana, in 

 the absence of the present writer, who then 

 held that chair. 



In 1892, Professor Dudley became professor 

 of systematic botany at Stanford University, 

 which position he held until, in January, 

 1911, failing health caused his retirement on 

 the Carnegie Foundation as professor emeri- 

 tus, his work being then taken by one of his 

 students. Associate Professor Le Eoy Abrams. 



Many of the leading botanists of the country 

 have been students of Professor Dudley. H. E. 

 Copeland, Kellerman, Lazenby, Branner were 

 among his associates at Cornell. Atkins be- 

 came his successor at Cornell. Abrams, Cook, 

 Elmer, Olssen-Seffer, Cannon, Wight, E. B. 

 Copeland, E. G. Dudley, Greeley, Herre, Mc- 

 Murphy and many others were under his tute- 

 lage at Stanford. 



In Stanford University, Dudley was one 

 of the most respected as well as best beloved 

 members of the faculty. No one could come 

 near to him without recognizing the extreme 

 refinement of his nature; a keen intellect, an 

 untiring joy in his chosen work, and the Puri- 

 tan conscience at its best, with clear percep- 

 tions of his own duties to himself and a gen- 

 erous recognition of the rights and the 

 aspirations of others. 



Dudley entered with great joy into the 

 study of the California flora. He became espe- 

 cially interested in the study of trees, the 

 evolutionary relations of forms and especially 

 the problems of geographical distribution. '
