Jerzy Franciszek Kulczycki of the Sas coat of arms (German: Georg Franz Kolschitzky, Ukrainian: Юрій-Франц Кульчицький, romanized: Yurii-Frants Kulchytskyi; 1640 – February 19, 1694) was a Polish nobleman, diplomat, and spy during the Great Turkish War. For his actions at the 1683 Battle of Vienna, when he managed to get out of the besieged city to seek help, he was considered a hero by the local people. According to legend, he is often cited as starting the first café in the city in 1683, using coffee beans left behind by the retreating Ottoman Turks. However, more recent sources suggest that the first coffeehouse in Vienna was opened by the Armenian Johannes Theodat in 1685.
