In 1894 German designers began to come up with new series of magazines. The first magazine Pan was published in Berlin in 1895 to promote the Art Nouveau in Germany. Julius Meier-Graefe (1867-1935) was one of its founders. Pan covered many favourite themes of Art Nouveau during its five years.
The second magazine Jugend was published in 1896 by the publisher Georg Hirth (1841-1916). This is from where the term Jugendstil was used.

Peter Behrens was German born in Hamburg, Germany on April 14, 1868. He died on February 27, 1940 (aged 71)
He was one of the leaders of architectural reform at the turn of the century and was a major designer of factories and office buildings in brick, steel and glass.
He designed the entire corporate identity (logotype, product design, publicity, etc.) and for that he is considered the first industrial designer in history.
