Joseph Wenzel (born 1696, died 1772) dedicated himself mainly to the soldier profession. The climaxes of his military career were his promotion as field marshal and as generalissimo in Italy (1745), as well as General Chief Commander in Hungary (1753).
The greatest military achievement was the reorganisation of the Austrian artillery system. He provided important parts of his private assets for the development of new cannons.
His military career was interrupted several times by diplomatic activities. In 1735/36 he operated as imperial envoy in Berlin. From 1737 to 1741 he was ambassador in Paris. He was the qualified man for these missions, thanks to his voluble and magnificent appearance.
