Serhii Oleksiyovych Buhoslavskyi[1] (Ukrainian: Сергій Олексійович Бугославський; Russian: Сергей Алексеевич Бугославский, romanized: Sergei Alekseevich Bugoslavskii[1][2] or Bugoslavskij[3]; Chernihiv, 2 July 1888 – Moscow, 14 January 1946) was a Russian Imperial and Soviet literary historian, musicologist and composer from present-day Ukraine.
He received his academic training at the seminar of East Slavic philology of Volodymyr Peretz [uk].
He studied music composition with Reinhold Glière, Oleksandr Oleksandrovych Illinsky, and Sergei Vasilenko.
From 1926 to 1930, Buhoslavskyi served as the artistic director of the All Union First Programme of the Moscow-based All-Union Radio.
In 1941,[4] Buhoslavskyi advanced a more systematic approach to textual criticism of the Primary Chronicle than Aleksey Shakhmatov, but his work was lost during World War II and only rediscovered decades later.
