Pavel Jacobi graduated from Mikhailovskaya Artillery Military School in 1860 and continued his education in Mikhailovskaya Artillery Military Academy. Soon he became a member of the socialistCircle of Artillerists-Chernyshevs that included such future prominent revolutionaries as Peter Kropotkin andPyotr Lavrov. Jacobi retired from the Army and studied at the University of Heidelberg.

After recovering he was the Chief of Staff of Insurgent formations in Galicia. After suppressing of the uprising Jacobi emigrated to Switzerland.

In 1864 Jacobi enters and in 1868 graduated from the Medical Department of the University of Zurich. 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. He also tried to introduce theories of Karl Marx into the field of forensic medicine. In Switzerland he married Varvara Alexandrovna Zaytseva, sister of Russian publicist Varfolomey Zaytsev (1842–1882).

In 1880 Jacobi writes an important article Morality in Psychiatric Statistics (Нравственность в психиатрической статистике). The statistical calculations for the article were performed by Russian mathematician Sofia Kovalevskaya.

He also participated in establishing psychiatric institutions in Kharkov, Kursk and Mogilev. Jacobi is credited to be the first who formulated the all the principles for the new paradigm in the organizational psychiatry towards Pinel ideas of non-confinement. 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.
