Sergey Prokudin-Gorsky
In 1920, Prokudin-Gorsky remarried and had a daughter with his assistant Maria Fedorovna née Schedrimo. The family finally settled in Paris in 1922, reuniting with his first wife and children. Prokudin-Gorsky set up a photo studio there together with his three adult children, naming it after his fourth child, Elka. In the 1930s, the elderly Prokudin-Gorsky continued with lectures showing his photographs of Russia to young Russians in France, but stopped commercial work and left the studio to his children, who named it Gorsky Frères. He died in Paris on September 27, 1944, a month after the Liberation of Paris. He is buried in the Sainte-Geneviève-des-Bois Russian Cemetery.
Sergius of Radonezh
In December 1937, Pavel Florensky (1882–1937), a Russian theologian, priest, mathematician, inventor, philosopher and engineer died in the Soviet Gulag and it is thought he was condemned by an extrajudicial NKVD troika under NKVD Order No. 00447 to be executed during the 1930s Bolshevik purges after refusing to disclose the hiding place of Sergius' head which the Bolsheviks wanted destroyed. It is rumored that Florensky and other theologians were involved in a plot to save and hide the relics of St. Sergius. The relics were returned by Pavel Golubtsov, later "Archbishop Sergius," to the Troitse-Sergiyeva Lavra (Trinity Cathedral) of the lavra in 1946 when it was reopened.
