Stefan de Leval Jezierski (Berlin, Germany),  was born  in  Boston and studied horn with Myron Bloom at the  Cleveland Institute of Music and at the  North Carolina  School of the Arts . While still a student he appeared as  a soloist with members of the  Cleveland Orchestra in  Severance Hall and was shortly there after appointed  principal horn of the  Kassel State Opera orchestra.

In 1978 at the age of twenty - three he was hired by  Herbert von Karajan and the  Berlin Philharmonic to  play high horn. Since then he has been a member of  the winds of the Berlin Philharmonic and co - founded the  Scharoun Ensemble. He is currently the longest serving  hornist of the  Berlin Philharmonic Orchestra (Berliner  Philharmoniker).

Appearing regularly as a soloist and chamber musici an at major music festivals and  concert venues throughout Europe, America, and Asia, he also teaches horn at the  orchestra academy of the Berlin Philharmonic and is professor H.C. at the  Shanghai  Conservatory.

His enthusiasm for playing jazz on the horn inspired him to form a jazz quintet with other  top North American players living in Berlin and has led to onstage improvisations with  notable musicians such as  Nigel Kennedy. Countless LP's, CD's, and video recordings  document his career.
