Johann Josef Wenzel Anton Franz Karl, Graf Radetzky von Radetz (Template:Lang-en; Template:Lang-cz; Template:Lang-sl; 2 November 1766 – 5 January 1858) was a Czech nobleman and Austrian field marshal. He served as chief of the general staff in the Habsburg monarchy during the later period of the Napoleonic Wars and afterwards began military reforms. A disciplined and fair man, he was so beloved by his troops that he was known as Vater ('Father') Radetzky. He is best known for the victories at the Battles of Custoza (24–25 July 1848) and Novara (23 March 1849) during the First Italian War of Independence.
