At the University of Vienna, he studied Akkadian, Aramaic, Ethiopian, Sumerian and Sanskrit, as well as the cuneiform used in Asia Minor, Mesopotamia and Persia.

In 1906, at Hattusa (modern Boğazkale, about 200 km east of Ankara) a German expedition found the archives of the Hittite kings in cuneiform, but in an unknown language.

While on active duty in the Austro-Hungarian army during World War I, Hrozný published in 1917 a description of the language showing that it belonged to the Indo-European family.

[2] In 1925 Hrozný led a Czechoslovak archaeological team that discovered 1000 cuneiform tablets containing contracts and letters of Assyrian merchants in the Turkish village of Kültepe, and excavated the nearby ancient Hittite city of Kanesh.

[4] To solve the mystery of the Hittite language, Bedřich Hrozný focused on a text passage that reads: nu NINDA-an ezzatteni watar-ma ekutteni.
