With a solid academic background in Belgium and France, he stood out as one of the pioneers of abstractionism in Brazil. He began his career with figurative paintings in a Cubist style, in which decomposed forms and delimited fields of color structure dramatic compositions, as in his series on the Passion of the Christ. Based in São Paulo from 1948 onwards, he transitioned to geometric abstraction, marked by constructive rigor, dynamic planes, and chromatic tensions, and later to the lyrical abstraction of organic forms, in which color, rhythm, and gesture predominate. In São Paulo, in 1951, he founded the Atelier-Abstração, an independent space dedicated to the research and teaching of geometric abstract art, which trained a generation of artists. He had a long relationship with the MAM São Paulo, where he participated in the inaugural exhibition. From Figurativism to Abstractionism (1949) and several collective and individual exhibitions, culminating in the major retrospective Samson Flexor: beyond modern (2022)
