The Henschel Quartet is a German string quartet comprising the Henschel siblings; Christoph and Markus (violinists; born 17 September 1969), Monika (violist; born 8 August 1968) and Mathias Beyer-Karlshøj (cellist), who joined them in 1994. Brother Markus left the quartet in 2010, and was succeeded by Daniel Bell in 2012.
Christoph, Markus and Monika Henschel studied with Felix Andrievsky, a graduate of the Moscow Violin School of playing (Yampolsky and Yankelevich) and gained distinction in their diplomas from the Royal College of Music, in London. Mathias Beyer-Karlshøj studied with the Swedish cellist Thorleif Thedeen and gained a distinction in 1996, at the end of his studies at the Royal Danish Academy of Music in Copenhagen.
An intensive musical experience was gained through their contact with Sergiu Celibidache and with Prof. Franz Beyer from the Musikhochschule in Munich. The London Master Classes and classes at the Musikhochschule in Cologne, Germany with the Amadeus Quartet had a determining influence on the musical development and direction of the ensemble. Similarly, regular courses with members of the La Salle Quartet and Alban Berg Quartet had a profound influence on the Henschel Quartet. The Henschel Quartet were quartet in residence at both the Aldeburgh Festival (1994) and at the Tanglewood Music Festival (1995/1996). At the latter, they were coached by musicians Louis Krasner and Eugene Lehner, who had worked with composers such as Béla Bartók and Arnold Schönberg, and who gave the quartet unique insights into the works of the Second Viennese School.
