Jeanne Matignon de Salzmann born Jeanne Allemand often addressed as Madame de Salzmann (1889 – 25 May 1990) was a close pupil of G. I. Gurdjieff, recognized as his deputy by many of Gurdjieff's other pupils. She was responsible for transmitting the movements and teachings of Gurdjieff through the Gurdjieff Foundation of New York, the Gurdjieff Institute of Paris and other formal and informal groups throughout the world.
Madame de Salzmann began her career at the Conservatory of Geneva, studying piano, orchestral conduction and musical composition. Later a student of Emile Jaques-Dalcroze in Germany from 1912, she taught dance and rhythmic movements. She met her husband Alexandre de Salzmann in Hellerau at Dalcroze's school. With him she had a daughter, Boussique. The Russian revolution triggered a move for Jeanne and her husband Alexandre to Tiflis, Georgia where she continued to teach.
In 1919, Thomas de Hartmann introduced the de Salzmanns to George Gurdjieff, a relationship that would last until Gurdjieff's death in 1949. She worked with Gurdjieff for nearly 30 years.
In December 1949, together with Henriette H. Lannes, Jane Heap she initiated the startup of an organization, which would eventually become the Gurdjieff Foundation, to continue the Gurdjieff Work. On 6 October 1955 The Society for Research into the Development of Man Ltd. was founded. This organization later changed to The Gurdjieff Society Ltd., on the 17 June 1957. She led the organization and continued Gurdjieffs teachings, emphasizing work with the movements, until she died, 101 years old in 1990.
