Pyotr Alekseyevich Golitsyn (1731–1810) Dmitri Alekseyevich Gallitzin (1734/8–The Hague, 1803) was a Russian diplomat, art agent for Catherine the Great. The idea of acquiring not individual pictures but large collections "en bloc" came from Golitsyn. He was the main driving force behind the subsequent painting acquisitions in France. He was the Russian ambassador in Paris (1762–68); a friend of Falconet, Denis Diderot, a supporter of the physiocrats, and translated Helvétius. He was envoy in The Hague (1768–98), a supporter of the League of Armed Neutrality, the recognition of the United States and the abolition of serfdom. After 1789 he continued to defend his principles and never returned to Russia. In 1768 he married Adelheid Amalie Gallitzin. In 1774 the couple split and the Princess moved to a country house between The Hague and the beach, to better to oversee raising her children in a way J.J. Rousseau had promoted in his "Emile". She turned to Catholicism in 1786. He is known as volcanologist and mineralogist. Prince Demetrius Augustine Gallitzin (The Hague, 1770–1840) also known as the Apostle of the Alleghenies, grew up with prince William I of the Netherlands. In 1792 he embarked to Baltimore. He was the first Roman Catholic priest ordained in America; a settlement in Pennsylvania is named after him. He is currently under investigation for possible Sainthood, his current title is Servant of God.
