Flexor began to paint with Sorokskaya landscapes, to the 1920s, almost en- tirely focused on portretistike, first performed in a realistic manner. Over the years, portrait work appear more pronounced expressionist features. The first solo exhi- bition of works by Flexor held 2 April 1927 in Brussels in the gallery Campagne Premiere, followed by a part in group exhibitions in Paris, during the 1930s, he regu- larly exhibited at the Salon des Surindépendants. In 1946 he first visited Brazil, and in the spring of 1948 he left France for good and settled in São Paulo. Since moving to Brazil realism completely disappeared from the works of the artist, and allhis further work was abstract. In 1951 Flexor opened the firstabstractionist studio in Brazil called Atelier-Abstração, where the exhibited works are united around him a group of Brazilian contemporary abstract painters Jacques Douchez, Norberto Nicola, Leopoldo Raimo, Alberto Teixeira, Wega Nery, Anésia Pacheco e Chaves, Charlotta Adlerová, Iracema Arditi and Gisela Eichbaum. In 1961 Flexor opened the second ab- stractionist studio. The only exception to the whole abstractionist art in Brazil during the frescoes were made by him in 1948 for the church of Nossa Senhora de Fátima and in 1958-1960 for the Church of Nossa Senhora do Perpétuo Socorro in São Paulo. In the last years of his life and during the 1970s the work of Samson Flexor regularly exhibited in Brazil in recent years has increased interest in his work and abroad.
