Klosé was second clarinet at the Théâtre Italien to Frédéric Berr beginning in 1836, then to Iwan Müller following Berr's death in 1838, finally becoming solo clarinet when Müller left in 1841.
Ivan Müller, sometimes spelled Iwan Mueller (1786 Reval, Estonia–1854 Bückeburg), was a clarinetist, composer and inventor who at the beginning of the 19th century was responsible for a major step forward in the development of the clarinet, the air-tight pad.
