Pyotr Leontievich Antonov (Russian: Пётр Леонтьевич Антонов) (21 December 1859–18 June 1916) was a Ukrainian-Russian revolutionary and terrorist, who survived 20 years imprisonment.
As a soldier's son, Pyotr's father was educated in a cantonist school, and worked as a bookbinder.
He was considered to be one of the party's best propagandists,[1] but gave up late in 1882 and joined the South Russian (i.e. Ukrainian) military organisation of Narodnaya Volya, and for nearly three years he was engaged fulltime as a terrorist.
In November 1984, he organised another attempt to rob the mail, during which a postal employee was killed.
In 1885, Antonov was betrayed to the police by a fellow party member named Pyotr Yelko, who had become an informer.
