Originally from Lille, in the north of France, Julien Mortier began his instrument-making career at the age of sixteen as a self-taught luthier. After working with master luthier Franco Simeoni in Italy, Julien decided to specialize in the creation and restoration of bows for quartet instruments, which has been his main focus since 2003. He honed his skills under the tutelage of bow makers Jean-Marc Panhaleux, Jean Grunberger, and Blaise Emmelin.
Since 2005, he has been living and working in the historic center of Perpignan, where he shares a studio with violin maker Sophie Erdal. In addition to producing new bows of the highest quality and restoring fine antique bows, he is dedicated to continuing his research to improve his skills by sharing ideas and information with trusted colleagues and by attending training seminars, conferences, trade fairs, and exhibitions.
