Jakob Zeugheer (known also as J. Z. Herrmann), (born Zürich 20 July 1803; died Liverpool 15 June 1865) was a Swiss violinist, conductor and composer.
Born at Zürich in 1803, Zeugheer learned the violin first from Wassermann in his native town, and in 1818 was placed at Munich under Ferdinand Franzel, for the violin, and Gratz for composition and musical science. A visit to Vienna in 1823 confirmed his enthusiasm for chamber-music and Beethoven, who remained through life the object of his highest veneration.
The example of Schuppanzigh, and of the four brothers Moralt, suggested to Zeugheer the idea of attempting the same with his friends in Munich, as "das Quartett Gebrüder Herrmann". Zeugheer was leader; Joseph Wex of Immenstadt, second violin; Carl Baader, viola; and Joseph Lidel (grandson of Andreas Lidel, the eminent performer on the baryton), violoncello. They started Aug. 34, 1824, for the south, and gave performances at the towns of south Germany and Switzerland, and along the Rhine to the Netherlands and Belgium. In the spring of 1826 they played in Paris, before Cherubini and Baillot, and gave a public performance assisted by Mile. Sontag and M. Boucher. They first performed in Paris Spohr's double quartet in D minor, the second quartet being played by Boucher and his three sons.
From Boulogne the quartet crossed the Channel; in England they seem to have been successful, at Dover, Ramsgate, and especially at Brighton, where they resided for five months. They gave concerts throughout the South and West of England, and in Ireland from Cork to Dublin, where they arrived in November 1827.
