Howaldt was born in
Braunschweig as the son of the silversmith David Ferdinand Howaldt. He learned silversmithing and went to
Nuremberg, where he became friends with the sculptor Jacob Daniel Burgschmiet, who convinced him to change to modelling and sculpture. He became a teacher in modelling there and continued teaching modelling when he returned to Braunschweig in 1836. The success out of his cooperation with the famous sculptor
Ernst Rietschel allowed him to start his own
foundry casting sculptures for many known German sculptors of the nineteenth century. Since 1863 he was professor at the
Collegium Carolinum zu Braunschweig, today
TU Braunschweig. Howaldt died in Braunschweig. His son
Hermann Heinrich Howaldt, also a sculptor, had joined him and continued his work and the foundry under
Howaldt & Sohn until his own death. His brother
August Howaldt was in 1838 the founder of the German shipyard
Howaldtswerke in
Kiel. ==Bronze castings==
