Pavel Jacobiy

Soon he became a member of the socialist Circle of Artillerists-Chernyshevs that included such future prominent revolutionaries as Peter Kropotkin and Pyotr Lavrov.

[1] He became a leader of the "Young Emigration" circle of the Land and Liberty society and published polemical political articles criticizing socialist Alexander Herzen for being to moderate.

[1] In 1880 Jacobiy writes an important article Morality in Psychiatric Statistics (Нравственность в психиатрической статистике).

It was done during a historical debate of 1891 about the future of Russian psychiatry and required expertise in both European new theories and psychiatric practice in contemporary Russia.

[3] One of the main ethnographic results of Jacobi at the time was discovering people of clearly Finnic descent, whom he attributed to be descendants of historical Vyatichs tribe.

His son, Ivan Palvovich Jacobiy was a notable political thinker of White Emigre, the author of the book Nicholas II and the Revolution (Tallinn, 1937).
