Work and influence

Chuprov was influential both as a teacher and as a writer. The curriculum he designed for the St. Petersburg Polytechnic Institute was modern and his book on the theory of statistics was influential. He had some good students, the best known was Oskar Anderson

  and Chuprov contributed to this research. (There is a brief account of the history of this theory in Heyde & Seneta (1977.)) A. I. Chuprov was the leader of a movement to get statistical information on social conditions in Russia. By 1910 his son A. A. Chuprov was writing about the use of random sampling in such investigations. His work paralleled that of Bowley

The richest source of information about Chuprov is Oscar Sheynin's article:
(The same website now [2007] also offers a downloadable version, in Russian, of the recently discovered Bortkiewicz-Chuprov correspondence 1895-1926.)

The MacTutor site does not have an entry for Chuprov but it has entries for Chuprov's 'masters', Bortkiewicz and Lexis, and his student, Oskar Anderson.

The photograph also appears on the Russian Academy of Sciences website, as does one of his father A. I. Chuprov.
