Bergson's work was a major influence on Gilles Deleuze, who wrote a monograph on him ("Bergsonism") and whose philosophical analyses of cinema ("" and "") develop his ideas. Following debates concerning the foundation of mathematics around the mathematician and philosopher Henri Poincaré (1854–1912), who opposed Bertrand Russell and Frege, various French philosophers started working on philosophy
