in the United States. The ''Life and Letters of William Barton 

 Rogers" (1896), in the preparation of which Sedgwick assisted 

 President Roger's widow, was a labor of love which expressed all 

 the loyalty of the Technology faculty and alumni to the great 

 founder of the Institute. "Principles of Sanitary Science and 

 the Public Health" (1902) was Sedgwick's most important lit- 

 erary production, a book which is still the best existing epitome 

 of the principles of sanitary science and which many academic 

 generations have found ''as interesting as a novel." "The 

 Human Mechanism," a textbook for schools and colleges, 

 published with Theodore Hough in 1906, marked Sedgwick's 

 return to his earlier interest in physiology and personal hygiene; 

 and "A Short History of Science," published with H.W.Tyler 

 in 1917, placed in permanent form the broad historical sense 

 and the keen love of origins which were always among the 

 greatest charms of Sedgwick's courses. 



Sedgwick's scientific attainments received recognition in the 

 conferring of the honorary degrees of Sc.D. by Yale in 1909, 

 and LL.D. by the University of Cincinnati in 1920, as well as 

 in election to the American Academy of Arts and Sciences and 

 the American Philosophical Society. He was appointed a member 

 of the Advisory Board of the United States Hygienic Laboratory 

 in 1902, and later received a cormnission as Assistant Surgeon 

 General in the United States Public Health Service. He was a 

 member of the International Health Board of the Rockefeller 

 Foundation. He was a founder and first president of the 

 Society of American Bacteriologists and our organization owes 

 its establishment and its broad charter more perhaps to him 

 than to any other individual. He served also as president of the 

 American Society of Naturalists, the American Public Health 

 Association, and the New England Water Works Association. 



Sedgwick's interests were, however, never narrowly bounded 

 by his own technical field. Wherever educational or civic 

 problems were to be solved he was ready to serve. A score of 

 progressive movements in Massachusetts numbered him among 

 their leaders. He w^as president of the board of trustees of 

 Sharon Sanatorium from 1902 and a member of the Public Health
