The quartet's composition remained "pretty constant until the mid-1860s".
At one point, the composition was:
- Joseph Hellmesberger, Sr. (1st violin)
- Adolph Brodsky (2nd violin), left Vienna in 1870
- Sigismund Bachrich (viola)
- David Popper (cello), from 1868 to 1870
Hellmesberger's son, Joseph Hellmesberger Jr. joined the quartet in 1870 to play the second violin and became leader in 1887.
Ferdinand Hellmesberger, the son of Joseph Sr. and brother of Joseph Jr., joined in 1883 to play the cello.
The Quartet played an important role in Vienna's musical life through the performance of quartets from Ludwig van Beethoven, Johannes Brahms, and Franz Schubert, premiering several of Brahms' and Schubert's chamber works.
