Information trouvée : He graduated tenth in the class of 1869 USMA and was commissioned a 2nd Lieutenant
of Artillery. His first duty was as Assistant Instructor of Artillery Tactics at West
Point from July 6 to August 28 in the summer of 1869. He was then stationed in Fort
Jefferson, Florida. In this period after the Civil War, there was little chance of
advancement in the army so, after consulting with General William T. Sherman, he resigned
in 1870. He served as a short period as an engineer locating routes for railroads.
Then he became a professor of Mathematics at Grinnell College where he stayed until
1873. Then he became Professor of Civil Engineering in the Chandler Scientific School
at Dartmouth, accepting the position on the condition that he be allowed to serve
abroad for a year [manuscript source listed below]. He went to Paris where he followed
the course of the Ecole des Ponts et Chausees as an eleve externe and simultaneously
attended as many of the lectures as he could at the Beaux Arts, Sorbonne, and Conservatoire
des Arts. In 1878 he obtained the chair of mathematics at Dartmouth and served until
1893. From 1893 to 1895 he served as a coeditor of Cosmopolitan magazine. Then in
1897 he began a period of eight years in the diplomatic service. He served as U.S.
minister to Persia (1897), Greece (1899-1901), Rumania (1899), Serbia (1899), Switzerland
(1901-1903), and Spain (1902-1905).
