Klaus Grünke learned the craft of bow making from his father Richard grünke, in Bubenreuth between 1974 and 1978. In the early 1980's, Klaus worked for Hans Weishaar in Los Angeles, focusing intensively on both restoration and the study of old master bows, and in 1980, won two gold medals for viola and cellos bows at the Violin Society of America competition. Klaus then returned to Bubenreuth to work with his father and brother, Thomas Grünke, also a bow maker.
In 1996, the Grünkes founded the company Richard Grünke & Söhne, where they currently restore and build bows for clients all over the world. Klaus Grünke developed his own bow models based on Dominique Peccatte, François Nicolas Voirin, and more recently, Nikolai Kittel. His bows have won the highest honors in international competitions, and he has served on the jury of numerous competitions. He is a member of Verband Deutscher Geigenbauer und Bogenmacher, Entente Internationale de Luthiers et Archetiers, and is a founding member of the International Pernambuco Conservation Initiative (IPCI).
In the year 2000, Grünke collaborated with bow making colleagues C. Hans Karl Schmidt and Wolfgang Zunterer to write and publish the encyclopedia "German Bow Makers." Grünke also co-authored the book "The Bows of Nikolai Kittel," published in 2011 with colleagues Josef Gabriel and Yung Chin. He is one of the world's leading living bow makers.
