Aleksandr Dmitrievich Dulichenko (alternatively Alexander DuliÃÂenko; ; 1941 â 6 March 2026) was a Russian-Estonian Esperantist, linguist, and expert in Slavic microlanguages who lived in Estonia. He was a professor at the University of Tartu, where he was the head of the department of Slavic studies.
Dulichenko was born in Krasnodar in 1941. He was the editor of Interlinguistica Tartuensis, a journal on interlinguistics published by the University of Tartu that published seven volumes from 1982 to 1990 recording the proceedings of colloquia at Tartu; in 2006, an eighth volume was published.
A festschrift in Dulichenko's honor was organized in 2006; Humphrey Tonkin calls this volume a "particularly important addition to the literature" of interlinguistics and Esperanto studies.
Dulichenko died on 6 March 2026, at the age of 84.
