ALBERT BENJAMIN PRESCOTT. 



Dr. Albert Benjamin Prescott, di- 

 rector of the chemical laboratory at the 

 University of Michigan, died at his home in 

 Ann Arbor, February 25, 1905. He was 

 the senior member of the university faculty, 

 and one of the veterans of American sci- 

 ence. 



Dr. Prescott was born at Hastings, N. Y., 

 December 12, 1832. Educated as a physi- 

 cian, he took the degree of M.D. in 1864, 

 and in that year and part of the year fol- 

 lowing, he served as an assistant surgeon 

 in the United States Volunteer Army. In 

 1865 he became assistant professor of chem- 

 istry in the University of Michigan; was 

 made full professor of organic and applied 

 chemistry in 1870 ; and was dean of the 

 school of pharmacy since 1870 ; and from 

 1884 to the day of his death, was director 

 of the chemical laboratory. His whole pro- 

 fessional life as a chemist was spent in the 

 service of the university, as teacher, organ- 

 izer, administrator and investigator dur- 

 ing a period of forty years. 



In a career like that of Dr. Prescott there 

 is nothing sensational or spectacular. It 

 was a life of obvious duties, uniformly well 

 done, with nothing slighted, and no stri- 

 vings after public recognition. Recognition, 

 nevertheless, came to him unsought, and he 

 had the satisfaction of knowing that his 

 work was appreciated. He became presi- 

 dent of the American Chemical Society, the 

 American Association for the Advancement 

 of Science and the American Pharmaceut- 

 ical Association ; honors as high as any that 

 American scholarship can confer. From
