László Seeman graduated in 1999 from the Franz Liszt Academy of Music (Budapest) as a student of Ádám Friedrich. After resigning from his post at the Northern German Radio Symphony Orchestra-Hamburg (a position he held from 1998-2003), as well as a subsidiary role in the Bayerische Rundfunk Orchestra in Munich, a sampling of activities offers evidence of Seeman's enduring stature as a french horn player of the highest echelon and renown. Seeman began placing in competitions in highschool, starting with a first-place finish in the National Conservatory Competition-Miskolc (1993) through his years at the Academy of Music in Budapest (Ph. Farkas Horn Competition, first prize) and on to the international platform, with wins in the Santa Barbara-based "American Horn Competition" (first prize), in France at Toulon (first prize) and the ARD Competition in Munich (second prize; first not awarded). Additional prizes include two third place finishes (where no first prizes was awarded) at Markneukirchen (1996) and at Prague (1997) while at Porcia (Italy) in 1998, Seeman won second (no first prizes awarded).
Seeman's experience with top-level orchestras has helped him to prepare a number of horn players for successful solo horn auditions with orchestras such as the RSO Vienna as well as the Hamburg Opera to name only a few. He has presented masterclasses in Japan, Italy, Slovenia, Croatia, Switzerland, the USA, as well as across Hungary. From 2004-2007, Seeman was a teacher at the Egressy Béni Conservatory of Music-Budapest as well as assuming an adjunct position at the St. István Király Conservatory-Budapest. Today he is teaching the horn at the University of Miskolc/Hungary.
