Sergey Prokudin-Gorsky
Sergey Mikhaylovich Prokudin-Gorsky (, ;  – September 27, 1944) was a Russian chemist and photographer. He is best known for his pioneering work in colour photography and his effort to document early 20th-century Russia.
Maxim Gorky
The sudden death of Gorky's son Maxim Peshkov in May 1934 was followed by the death of Maxim Gorky himself in June 1936 from pneumonia. Speculation has long surrounded the circumstances of his death. Stalin and Molotov were among those who carried Gorky's coffin during the funeral. During the Bukharin trial in 1938 (one of the three Moscow Trials), one of the charges was that Gorky was killed by Yagoda's NKVD agents.
