This article is devoted to the life and work of the ethnic German philosopher Julius Hecker, the scholar and public figure who contributed to Soviet Russia by attracting the humanitarian aid and helping to reform the educational system. Eventually, he was murdered by the Stalinist regime as «the imperialists’ spy and people’s enemy» and most of his family members were also unjustly repressed. Professor J. Hecker was rehabilitated on April 18, 1957, posthumously. He was a grandfather of an outstanding Russian archaeologist and Kyrgyz study scholar, Professor Yuli Sergeevich Khudiakov, who was named as «Yuliy» after him.
