He was born in Bad Kreuznach to sculptor Karl Cauer, who gave him his first lessons.
That same year, he created one of his largest works, the monument "Michel Mort und die Schlacht von Sprendlingen" (Michel Mort and the Battle of Sprendlingen [de]) in Bad Kreuznach.
After another stay in St. Louis in 1904, he settled in Darmstadt and worked as a freelance sculptor; producing busts and reliefs for public and private clients, many with religious or symbolic themes.
In 1916, he was awarded the title of Professor by Grand Duke Ernst Ludwig, and became an honorary citizen of Hesse the following year.
