In 1795 Georg Friedrich Parrot came to Livonia into the house of a noble man as a house teacher. He became the educator of the two sons of the count Karl Eberhard von Sievers (1745-1821) in Wenden. Soon after he was appointed to be the first secretary of the Livonian Charitable and Economic Society in Riga. In Riga he started his research on the osmosis. Some years later he left Riga for Dorpat to become the founding Rector of the University which had been re-founded by Tsar Alexander I. in 1802, but he stayed in contact with Riga. In 1812 Napoleon waged war on Russia and part of his troupes reached the Daugava. When that happened the commander of the town of Riga von Essen ordered to put the fire to the suburbs outside the city walls of Riga. In consequence all the now homeless inhabitants took refuge within the city walls which provoked an outburst of different sicknesses. At the same time wounded people from Napoleon’s war were brought into the town. Confronted with these difficulties the commander von Essen asked the University Dorpat for help and Parrot decided to send some medical students and doctors to go to Riga and help out. Among the students who went was the son of Parrot Friedrich Parrot (1791-1841) and the student Karl Ernst von Baer (1792-1876) who later became famous and was called the ‘’Alexander Humboldt of the North’’. Not all students returned safe to Dorpat, they had some fatalities. Parrot was not only a scientist and the rector of the university but he was one of the people engaged in the liberation of the Latvian and Estonian farmers who lived in serfdom. He had contacts with personalities who were influenced by the enlightenment movement like Friedrich von Sievers, G. Merkel and the Pastor K.G. Sonntag. He was in an intensive relationship with Tsar Alexander I. and F. von Sievers about this question and it is still not very clear how far his influence reached into the decisions of the Tsar. The relationship of Parrot and his family to Riga is very strong. In 1796 he married his second wife in the Jacobi church in Riga. One of his sons, Wilhelm Friedrich Parrot (1790-1882) became a pastor in Burtnieki (1817-1860) and got married in the Jacobi church in 1818. One of the grandsons of G. F. Parrot was the actor Piers Friedrich Parrot (1838-1925). He was the artistic director of the theatre of the town of Riga (1869-1874). His other grandson, the brother of the before mentioned, Moritz Friedrich Parrot (1831-1882) had been a pupil of the famous Gymnasium at Birkenruh near Cēsis, he later became a physicist.
