In 1869, the Joachim String Quartet was formed, which quickly gained a reputation as Europe's finest. It continued to perform until Joachim's death in 1907. Other members of the Quartet were Karel Halíř (2nd violin) from 1897 on; Emanuel Wirth (viola) from 1877 on; and Robert Hausmann (cello), from 1879 on. In 1878 while writing his violin concerto, Brahms consulted Joachim, who "freely gave him encouragement and technical advice". Brahms asked Joachim to write the cadenza for the concerto, as he did.
