Born in
Braunschweig, the son of the silversmith David Ferdinand Howaldt, with whom he got his first practice working in metal, Howaldt made an apprenticeship in
Hamburg and became a
practical mechanicus. In 1838 he moved to
Kiel, where he married Emma Diederichsen. In Kiel he founded together with the Kiel entrepreneur the "Maschinenbauanstalt Schweffel & Howaldt", a company initially building boilers for industry and the new railroad companies in between Hamburg and Kiel and agricultural machinery for the surrounding estates in
Holstein. In 1849 Schweffel & Howaldt built its first steam engine for naval purposes for the
Von der Tann, a gunboat for the small navy of
Schleswig-Holstein, and the
Brandtaucher, the first German incendiary diver or
submarine designed by
Wilhelm Bauer. The
Brandtaucher is today an exhibit of the
German Forces Military History Museum in
Dresden. Schweffel & Howaldt also built two tugs in 1860 and 1864. When he passed his company to his sons Georg, Bernhard and
Hermann Howaldt, who continued in 1879 under the name Gebrüder Howaldt. The firm merged with Georg's shipyard in Kiel in 1889 to become Howaldtswerke AG, today known as
Howaldtswerke-Deutsche Werft (HDW). ==References==
