Jan Kupecký
Ján Kupecký or Jan Kupecký (in German: Johann Kupetzky, in Hungarian: Kupecky János, or Kupeczky János, 1667 – July 16, 1740) was a Czech portrait painter during the baroque. He was active in Hungary, Vienna and Nürnberg. Bernhard Vogel produced many engravings after Kupecký's paintings. Life 
Kupecký, like many people at that time,  was the son of Protestant (Czech Brethren) parents from the Czech lands (Mladá Boleslav) who sought refuge in  Royal Hungary from religious persecution by the Catholics. He was born in Pezinok – a town near Pressburg. According to the sources he began his studies with the Swiss painter Benedikt Klaus, who was active in both Vienna and in Royal Hungary. At the age of twenty, Kupecký went on a long Italian study trip. In Rome Prince Aleksander Benedykt Sobieski, the son of the Polish king John III Sobieski, helped him to become famous. He returned to Vienna in 1709, after twenty-two years spent in Venice and Rome. We know little of his Italian activity as well as his early works and his setting in Vienna. According to his contemporary biographer, the Swiss Johann Caspar Füssli, the Protestant Kupecký, who faithfully clung to his ancestor's religion, remained withdrawn and isolated in Vienna's Catholic milieu, which was under the influence of the court and the aristocracy. However this concept is partly contradicted by the fact that the master had significant courtly commissions while working in Vienna. He painted portraits of various members of the dynasty, Prince Eugene of Savoy, several aristocrats, and, in Karlovy Vary, even of the Russian Czar Peter I. The rich oeuvre of this period comprises a series of gorgeous portraits of Kupecky's family, friends and the painter himself, as well as several persons, whose identity in unknown. In 1733 Kupecký, fearing religious persecution, fled from Vienna to Nuremberg with his family and worked there until his death in 1740. As the most significant portrait painter of contemporary Germany, he was commissioned by many German princes, church dignitaries rich merchants and scholars, and his works were popularized by engravings even during his lifetime. Through his pupils and followers Kupecký's influence and artistic example remained alive and widespread for a long time. Work 

His inspirations were Caravaggio, Reni and Rembrandt. His paintings include:
Portrait of Peter I of Russia
Portrait of Alexei Petrovich, Tsarevich of Russia
