Ferdinand Lassalle
Sergei E. Shevitch was born in Russia in approximately 1848. Of noble birth and radical political proclivities, Shevitch attended university in Russia before emigrating to Paris. It was there that he met and married the former Helene von Racowitza, over whom socialist leader Ferdinand Lassalle lost his life in a duel in 1864. The pair emigrated to the United States in 1877.
