Wilhelm von Roggendorf
Wilhelm Freiherr von Roggendorf (1481–1541) was an Austrian military commander and Hofmeister.
Wilhelm von Roggendorf served the Habsburgs starting in 1491. He was Stadtholder of Friesland between 1517 and 1520, and was in the second half of the 1520s Hofmeister of Ferdinand I, Holy Roman Emperor. During the Siege of Vienna in 1529 by the Turks, he served as commander of the heavy cavalry under his brother-in-law Nicholas, Count of Salm (1459–1530). In the following years he had an influential role at the Austrian court as Obersthofmeister. He resigned in 1539, but returned as commander of the Austrian Siege of Buda (1541), which ended in disaster. Von Roggendorf was wounded during this battle and died two days later of his wounds.
