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.

On 30 August, Boris Savinkov and Maximilian Filonenko ordered a military cadet named Leonid Kannegisser—Filonenko's cousin—to shoot and kill Moisei Uritsky, head of the Petrograd Cheka. Uritsky had been the second most powerful man in the city after Grigory Zinoviev, the leader of the Petrograd Soviet, and his murder was seen as a blow to both the Cheka and the entire Bolshevik leadership. After killing Uritsky, a panicked Kannegisser sought refuge either at the English Club or at the British mission where Cromie resided and where Savinkov and Filonenko may have been temporarily in hiding. Regardless of whether he fled to the English Club or to the British consulate, Kannegisser was compelled to leave the premises. After donning a long overcoat, he fled into the city streets where he was apprehended by Red Guards after a violent shootout.
