Todleben, Eduard Ivanovitch, a noted Russian general of German descent, who, trained in the engineer corps, greatly distinguished himself by his defensive operations at Sebastopol during its siege by the French and English in the Crimean War, and subsequently by the reduction of Plevna, his greatest achievement, which brought to a close the war with Turkey in 1877; subsequently became commander-in-chief in Bulgaria (1818-1884).
