Hochmeister Hartmann
         von Heldrungen
 
 Hartmann von Heldrungen (died 19 August 1283) was the 11th Grand Master of the Teutonic Order, serving
         from 1273 to 1283. Von Heldrungen was an Imperial Knight from Thuringia in the Holy
         Roman Empire. He joined the Teutonic Order along with
         his brother Hermann von Heldrungen between 1234 and 1237. In 1238, von Heldrungen became the Komtur in Saxony. He took part in diplomatic negotiations
         and celebrations when the Livonian Order  joined the Teutonic Order. He was trusted by the Grand Masters
         and  because of that, he was able to advance quickly within the Order.  Between 1261 and 1266, he was the Grand Komtur and
         second in charge  after the Grand Master, Anno von
         Sangershausen.
 
 
  Von Heldrungen became the 11th Grand Master in
         the summer of 1273.  His reign was marked by relative peace for the order, and he encouraged  the colonization of Prussia
         and Livonia. He gained more lands in the empire as well as in Pomerania. He died at Acre in 1283 after fifty years in the
         order and reportedly at close to a hundred years in age.
