The Zimbler Sinfonietta, founded in 1947 by the late Josef Zimbler, cellist of the Boston Symphony Orchestra, was one of the first string groups to perform without a conductor. From its beginning it enjoyed a success which was greatly enhanced by an annual series of concerts presented at Jordan Hall in Boston and its numerous recordings under the labels of Decca, Boston, Unicorn, and RCA Victor, which featured such outstanding soloists as Lukas Foss, Reginald Kell, Joseph and Lillian Fuchs, James Pappoutsakis, James Stagliano, Sherman Walt, and George Zazofsky. In 1957, a South American tour sponsored by the U. S. Department of State won great acclaim for this organization.
Following the death of its founder in I960, the Zimbler Sinfonietta was re- organized and George Zazofsky was appointed its permanent Musical Director.
The Chamber Orchestra Society of Philadelphia has recently honored this group by requesting a performance in its series for next season to be given at the Academy of Music.*
