Jürgen Dehmel (born 12 August 1958)[1] is a German bass player and songwriter.
He was born in Berlin. Dehmel was brought by keyboardist Uwe Fahrenkrog-Petersen to join the rock band Nena in 1981. Fahrenkrog-Petersen and Dehmel had previously been together in a band called Odessa, releasing a self-titled album in 1980. The band also included Helmut Hirt on vocals, Otto Schneider on drums, Bernd Däumchen on guitar and saxophone, and Andreas Römer on solo-guitar.
Dehmel joined Nena in 1981, and he remained until the band split in 1986. He continued to collaborate with Nena in her solo career and on tour, co-writing several songs for her solo albums. In 1986 Nena and Dehmel produced an album for the band Time Boys, under the names of Jay-Dee and Susi K. He also wrote songs and produced soundtracks for German films, and toured frequently with the singer Nina Hagen. In 1988 - 89 he also wrote three songs with his girlfriend, Ilonka Breitmeier, for a Bosnian-American pop star called Tinka. In 1991, he co-produced the album The Band (a collection of Nena's best songs). He usually works from his home-built recording studio.
Dehmel was married to Nena's sister, Kristiane, from 1985 to 1987. Kristiane was a nurse at a hospital in Berlin.
