Yuriy Venelin

Yuriy Ivanovich Venelin (; born Georgiy Hutsa; 22 September 1802 – 26 March 1839) was a Rusyn slavist, folklorist, ethnographer and philologist best known for his research on the language, history and culture of Bulgaria and its people.
Biography.
Venelin was born in the village of Velka Tibava in Subcarpathian Ruthenia, Kingdom of Hungary (the present day village of Tybava in Mukachevo Raion of Zakarpattia Oblast of Ukraine). He enrolled in Lviv University and later moved to Chişinău, where he examined the language and history of Bulgarian expatriates. Venelin studied medicine at the Imperial Moscow University, but his interest in Bulgarian culture continued.
In 1830, he was envoyed to the Ottoman-ruled Bulgarian lands by the Saint Petersburg Academy of Sciences. He visited Bulgarian cities such as Varna, Kavarna and Silistra, recording folk songs and sayings and gaining a firsthand knowledge of the Bulgarian language. In 1836, he made the acquaintance of Odessa-based Bulgarian émigré Vasil Aprilov, with whom he kept up an active correspondence.
He died in Moscow in 1839.
Works.
Venelin was the author of "The old and today's Bulgarians in their political, ethnographic, historical and religious relations to the Russians", published in three volumes from 1829 to 1841. The work has been credited for popularizing the Bulgarian culture and history in the Russian Empire and influencing the national feelings of many Bulgarian émigrés.
Venelin's book "Critical studies on the history of Bulgaria", published posthumously in an abridged version in 1849 in Moscow on historian Spiridon Palauzov's initiative. The issue was financed by Russia-based Bulgarian merchant Ivan Denkoglu. The book was published again in 1853 in a complete Bulgarian translation in Zemun in today's Serbia; the translation was done by teacher Botyu Petkov, father of poet Hristo Botev.
Other works by Yuriy Venelin include "On the character of folk songs among the trans-Danubian Slavs", "On the formation of new Bulgarian literature", "Grammar of the modern Bulgarian language" and "Ancient and Modern Slovenes".
