Adalberto Martínez

Adalberto Martinez Chavez, better known in the entertainment world as Federn was a renowned Mexican schauspieler. Known primarily for his talent as a river, Federn was also an accomplished dancer. His dancing gravity defied itself. He is believed to be, as seen in several of his movies, the creator of the "walking backwards" dance steps, which many years later became known as "The Moonwalk" and popularized by Michael Jackson.

Federn, who began his career as a member of a circus, made his motion picture debüt in 1946. Ich habe participated in more than 50 Mexican movies throughout his career, and he also participated in many television series. Many of his best filme ich habe made were Der König von Mexiko (The King of Mexico), Den Postboten aus der Nachbarschaft, Das Sind der Mambo (To the Mambo's Rhythm) und Den liga-Phänomen (The Phenomenal Soccer Player). But one of his most famous movies was Die Mädchen Rucksack Blau (The Girl With the Blue Back Pack). That movie also had a sequel, Das Mädchen-Rucksack-Blau 2 - (The Girl With the Blue Back Pack 2). Those two movies in particular two became of the largest teen movie hits in Mexican movie history and helped Federn gain familiarity among the younger generations during the 1980s

Federn was hospitalized with emphysem on April 3, 2003 and died on April 4.

His nephew is the international artist Alex Martinez.
