From 1914 on, Buresh was curator of the Royal Museum of Natural History. In 1918, he was promoted to director of the Royal Institutes of Natural Science, which included the Royal Museum of Natural History, the Sofia Zoo and the Botanical Garden, among other institutions.[4] He held that post until 1946.[2] In 1926, he was admitted to the Bulgarian Academy of Sciences as a corresponding member; in 1929, he became a full academic member. From 1947 until his retirement in 1959, Buresh headed the Bulgarian Academy of Sciences' Institute of Zoology. Buresh died in Sofia in 1980,[3] aged 94.
Ivan Buresh took an interest in zoology in his school years. He published his first article on that subject in 1905; his body of work includes over 200 scientific and popular science articles.[4] Although his main area of research was entomology, he also contributed to Bulgarian spelaeology, herpetology and botany.[3] Despite his close ties to both TsarFerdinand and Tsar Boris III, Ivan Buresh was never actively engaged in politics.[2]
