CHARLES ROBEKT SANGER. 819 



His first year after <2;ra(l nation was passcnl in study for the degree 

 of Master of Arts with Professor Hill, to whom he returned after his 

 year (188:2-1883) in Europe. He took his decree of Doctor of I'liil- 

 osophy in 1884, after whieh he served as Assistant in Clieniistry in 

 Harvard College, until in 1886 he was appointed Professor of Chem- 

 istry at the United States Naval Academy at Annapolis, a post for 

 whieh he was especially fitted by nature, or j)erhaps rather hy inheri- 

 tance. In 1892 he accepted tiie better position of Eliot Professor of 

 Chemistry at the \Vashington University of St. Louis. 



In 1899 Professor Hill found the duties of Director of the Chemical 

 Laboratory of Har\ard College so exacting, that he was forced to 

 give up the large elective in qualitative analysis (Chemistry 3) which 

 he had taught for many years. We considered this course, as devel- 

 oped by him, our most precious treasure, since it trained men in ob- 

 servation and inducti\e reasoning better than any other known to us, 

 but on the other hand, if improperly taught, it would sink to a mechani- 

 cal routine worthless for educational purposes. It became therefore 

 a matter of gra\e anxiety with us to find a successor for Professor Hill 

 in this course, who should be able to carr^• it on worthilv; and after a 

 careful search of the whole field we decided that Sanger was by far 

 the best man, and accordingly he was called to Harvard University 

 as Assistant Professor of Chemistry in 1899; and in keeping the work 

 in qualitative analysis on its previous high level he more than justified 

 our faith in him. 



As a teacher he was somewhat austere; all his stuflents were ex- 

 pected to live fully up to his own standard, and he always retained 

 some touch of the naval discipline. In particular research with him 

 was no easy matter — the same accuracy, the same thoroughness, the 

 same limitless patience, that he showed in his own work, he demanded 

 of his stu<lents, but, as they saw he required nothing from them, which 

 he did not exact from himself in e\en greater measure, they worked 

 with enthusiasm, and felt for him an affection perhaps even deeper 

 and stronger, than would have been inspired by an easier teacher. 



An additional reason for his appointment at Cambridge had been 

 that he was excellently fitted to act as director of the laboratory, 

 should this become necessary. The death of Professor Hill in 1903 

 brought this necessity only too soon, and led to liis appointment as 

 Director, and promotion to a full professorship. I have already 

 <lwelt on the self-sacrificing devotion shown by him in this position. 

 In all other respects too he proved an ideal choice, wise, and prudent 

 in planning the work, methoilical, thorough, and efficient in doing it.
