Ludwig Heinrich Freiherr[1] von Nicolay (Russian: Андре́й Льво́вич Никола́и, romanized: Andréj L'vovič Nikolái; 25 December 1737, in Strasbourg – 18 November [O.S. 6] 1820, in Monrepos north of Vyborg) was a German poet of the Enlightenment. He served as President of the St. Petersburg Academy of Sciences between 1798 and 1803.
Nicolay was the son of a Strasbourg archivist. He graduated from the University of Strasbourg with a degree in law. Like his father, he served as a librarian to a string of rich nobles. Prince Dmitry Gallitsyn employed Nicolay as his secretary in Vienna and Paris where he came to know Voltaire, Diderot, d'Alembert and other intellectuals of the Enlightenment.
In 1769 Nicolay was invited to the Russian Empire to be a teacher of logic for the future Emperor Paul I of Russia. In 1782 (on the same day as Goethe) Nicolay was ennobled and granted the title of baron by Joseph II. When Paul became emperor, he appointed Nicolay to run the St. Petersburg Academy of Sciences (15 April 1798 – 2 June 1803).
Nicolay's private library, collections (cameos, letters and other documents) and pictures are now in the possession of the Finnish National Library in Helsinki. This library is a very rare example of Russian libraries from the age of Enlightenment.[2]
In 1803 Baron von Nicolay settled into retirement at his estate Monrepos north of Vyborg. This estate belonged to the Nicolay family from 1788 to 1944 (when Vyborg was subsumed into the Soviet Union).
