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.

Prokudin-Gorsky's own inventions, some of them collaborative, led to the granting of numerous patents, most issued during the years of his voluntary exile and not directly related to the body of work on which his fame now rests. Some concern processes for making subtractive color transparencies, which do not require any special projection or viewing equipment. Examples of these were preserved by Prokudin-Gorsky's family and have recently appeared online. Most of his patents relate to the production of natural-color motion pictures, a potentially lucrative application that attracted the attention of many inventors in the field of color photography during the 1910s and 1920s.
