Yevgeny Prigozhin made his name as the profane and brutal mercenary boss who in June mounted an armed rebellion that was the most severe and shocking challenge to Russian President Vladimir Putin's rule. Prigozhin was aboard a plane that crashed north of Moscow on Wednesday, killing all 10 people on board, according to Russia’s civil aviation agency. The 62-year-old's extraordinary journey took him from prisoner and hot dog vendor to elegant St. Petersburg restaurateur, and then from propaganda wars to the grisly battlefields in Ukraine.
