Kunz or Konrad Lochner, the most important Nuremberg armourer of his era, was born in about 1510, the son of an armourer of the same name. His brothers Heinrich and Hans followed the same trade. In 1543 he was working for the future Emperor Ferdinand I and in the following year became court armourer to the future Maximilian II, for whom he made an armour still at Vienna (Hofjagd -und Rustkammer A529). A series of armours -two of which are dated 1550 and 1552 respectively- made by him for Johann Friedrich II of Gotha, was formerly at the Wartburg; at least part of this important series is now in St. Petersburg. Lochner made a gilt and cold-enamelled armour for man and horse for King Sigismund II August of Poland, now in Stockholm (Livrustkammaren 2603), and probably a similar armour for the king's brother-in-law Nikolaus 'the Red' Radziwill, Duke of Birze and Dubinki, d. 1584 (Hofjagd -und Rustkammer A1412). Lochner died in 1567. His mark is a lion rampant within a shield-shaped punch.
