was not small. He early took a stand among 
the foremost investigators of the country, and 
his work met with generous appreciation 
abroad. On invitation, he delivered an ad- 
dress at the St. Louis Congress in 1904 and a 
lecture at the Fifth International Congress of 
Mathematicians at Cambridge, England, in 
1912, and he was exchange professor at Paris 
in 1913-14. 
His life was lived within the academic walls, 
and while he took keen interest in current 
events of the world about him, his contact with 
men outside of university circles was not 
broad, and his judgment of them was some- 
times severe. But when opportunity presented 
itself to help in time of trouble, he was quick 
to respond. He sought relaxation from scien- 
tifie labor in literature, philosophy and music, 
rather than in social gatherings. 
Those who stood nearest him will remember 
“him best for the singleness of his purpose, the 
constancy of his effort, and the greatness of 
his ideals.
