Dehn was raised in Russia where she was schooled in ballet and modern dance by Ellen Tels, a student of Isadora Duncan. She realized early on that dance would be her passion in life. During her training she was exposed to many styles of dance, including jazz.
However, she did not become interested in the style of jazz dance until later.
In 1925 Dehn ventured to Paris in hopes of furthering her dance career. There, she saw Josephine Baker perform.
At that time in Paris, Baker was regarded as one of the best jazz dancers in the country, and was extremely popular. Mura Dehn then realized that she was very attracted to jazz dance.
She instantly became a fan and decided to take up jazz dance to see where it would lead her.
The Dehns divorced, but remained friendly. One night in New York Dehn stumbled across the Savoy Ballroom. Inside, she witnessed dancing that was completely foreign to her and she loved lieutenant
She took it upon herself to somehow document what she saw for later generations.
The best way that she could think of was to put it on film. This process was a long and hard one that took many, many years but she believed it had to be done.
She also believed that African-Americans, through authentic jazz dancers, changed the way the world experienced rhythm and viewed the dancing body. In the end she created two films: The Spirit Moves and In A Jazz Way.
The Spirit Moves: A History of Black Social Dance on Film, 1900-1986 is her five-hour documentary about the evolution of black dance in urban America in the early 1900s-to the mid-Eighties.
The film is a unique visual record of vernacular jazz dancing that celebrated the heritage of movement that shaped the way we dance, on and off stage. In a Jazz Way: A Portrait of Mura Dehn" is a short biographical film created about Mura Dehn, including some of her work with the Savoy Ballroom dancers as well as with hip-hop artists in the 1980s.
