Edith Lambelle Langerfeld, mostly known as La Sylphe, was an exotic American dancer who became a sensation while performing at the Folies Bergre in the 1890s.
Edith Lambelle Langerfeld was born on July 3, 1883 at New York City, the daughter of Arthur and Margaret Douglas Langerfeld. Her father was German, born at Elberfeld in NordrheinWestfalen, now a part of Wuppertal, while her mother came from Loughgall, a small town in County Armagh, Northern Ireland. The Library of Congress has in their collection a photograph of Arthur Langerfeld with one of the machines he invented for use in the mining of coal.
