The Flonzaley Quartet, a pioneering American string quartet, captivated audiences from 1902 to 1929. Founded and funded by New York banker Edward J. de Coppet, the quartet took its name from de Coppet's residence near Lausanne. The ensemble, originally comprising Alfred Pochon, Adolphe Betti, Ulrich Ara, and Isabelle d'Archambeau, was renowned for its refined performances of classical masterpieces by Haydn, Mozart, and Beethoven. They made their first recordings in 1913 and continued to release discs until their disbandment. The Flonzaley Quartet also championed contemporary composers, introducing works by young artists like Ernesto Halffter. Their legacy endures through their influential recordings and contributions to the string quartet repertoire.
