He won the competition in 1866 for a monument to Maximilian II of Bavaria, for the Maximilianstraße, Munich (unveiled 1875).
His most important works are a statue of Count Rumford, Munich; and the monuments to Prince August of Prussia (Bellevue Park, Berlin), Beethoven (1873-1880, Vienna), Maria Theresa (1887, Vienna), and to Emperor William I (1896, Wittekindsberg, Westphalia).
He also modeled many private funeral monuments, decorative works, and portrait busts, including one of Wagner.
