The Cosmic Movement was the organisation established by Max Théon around 1900, in Tlemcen, Algeria, at the instigation of his wife Alma Théon, whom he declared to be the moving spirit behind the group. Its journal was the Cosmic Review. Other publications included the Cosmic Tradition, and other works of the Cosmic Philosophy.
Among the most important of Théon's students at this time, who were involved in the Cosmic Movement, in Tlemcen and later in Paris, were Charles Barlet, Mirra Alfassa, Paul Richard, and Louis Themanlys.
According to Pascal Themanlys, other active contributors of the Cosmic Movement included Rene Caillie, the writer Marc Semenoff, the typesetter Jacques Janin, the painters Jacques Blot and Louis Bouchet, the architect Louis Berthaud, Maurice Ben Haroche, the Baroness of Eichthal, among others.
