31 December 1906] in St Petersburg) was a notable Estonian folklorist, theologian, and linguist.
With respect to the last, he is perhaps best known for his dissertation on "pure" -ne stem nouns ("Die estnischen Nomina auf -ne purum", 1886).
He was also featured on the 10 krooni note.
Also known as the "king of Estonian folklore", Hurt planned the publication in the 1870s of a six volume series called Monumenta Estoniae Antiquae.
Hurt organised around 1400 volunteer collectors via a press campaign, who visited almost every house in Livonia collecting around 124,000 pages of folklore.
Due to financial difficulties, however, only two volumes of folk songs were published in 1875-76, entitled Vana kannel (Old Zither).
Two more volumes were published in 1938 and 1941.
Hurt also published a three volume collection called Setukeste laulud (The Setus' Songs) between 1894 and 1907.
