Ivan Tkalčić

Ivan Krstitelj Tkalčić (4 May 1840 – 11 May 1905; "Ivan Krstitelj" is the Croatian name for John the Baptist) was a noted Croatian historian and a Catholic priest and prebendary.

Tkalčić was born on 4 May 1840 in Zagreb, Kingdom of Croatia, to father Janko from Samobor and mother Bara née Martinjakova. He was ordained a priest on 7 September 1862, becoming a curate in Sisak. On 10 October 1867, when he became the prebendary of the Zagreb Cathedral, a post he held until his death on 11 May 1905. His first publication was an article in Narodne novine in 1859. This was followed by many works pertaining history, especially the history of Zagreb and the Croatian church. Tkalčić became a corresponding member of the Croatian Academy of Sciences and Arts (then Yugoslav Academy of Sciences and Arts) in 1875, and a full member in 1882. From then onwards he held the position of the academy's librarian until 1892 and archivist in 1896.
