Julius Egghard was an Austrian violinist, born in Vienna on November 11, 1858. He was the son of Julius Egghard Sr.
He graduated from the Vienna Conservatory in 1875, where he studied with Karl Heissler. He gave his first concert in 1876, followed by extended tours across Europe.
In 1882, Egghard became the second violinist in the first string quartet led by Arnold Rosé; the group remained active until its reorganization in 1884. From 1887 to 1901, he played second violin in the Hellmesberger Quartet.
He performed with the Vienna Philharmonic Orchestra from 1886 to 1909 and with the Vienna Court Chapel from 1894 to 1915. From 1897, he taught at the Vienna Academy of Music, first as an assistant to Josef Maxinczak and later independently. One of his early students was the young Rudolf Kolisch. Egghard died in Vienna on November 23, 1935.
