The original Soldat Quartet was comprised of Marie Soldat, Marie Schumann, Gabriele Roy, and Lucy Campbell in 1887-88. All were from the Hochschule. After a few years, during which she married and had a child, Soldat reconstituted her group, which was based in Vienna from 1895 to 1914, and comprised of Ella Finger-Bailetti, Nathalie Bauer-Lechner, and Lucy Campbell.
