The paper presents for the first time abundant data on the history of the National Museum of Natural History at the Bulgarian Academy of Sciences in Sofia about one of the most difficult periods of that Museum, between 1959 and 1965. In that time the Museum was closed for visitors (1964-1968), its exhibition was drastically reduced and its rank was lowered up to section level of the former Institute of zoology, headed by the Assoc. Prof. Nikolay Boev .
