Émile Meyerson (French: [mɛjɛʁsɔn]; 12 February 1859 – 2 December 1933) was a Jewish Polish-born French epistemologist, chemist, philosopher of science and Zionist activist.

Meyerson was educated at the University of Heidelberg and studied chemistry under Robert Wilhelm Bunsen.

He served as foreign editor of the Havas news agency, and later as the director of the Jewish Colonization Association for Europe and Asia Minor.

He became a naturalized French citizen after World War I. Thomas Kuhn cites Meyerson's work as influential while developing the ideas for his main work The Structure of Scientific Revolutions.

[4] In La Déduction relativiste, Meyerson expressed the view that Einstein's general theory of relativity was a new version of the identification of matter with space, which he considered "the postulate upon which the whole (Cartesian) system rests.
