Leonid Savelievich Lipavsky and Yakov Semyonovich Druskin were two philosophers closely associated with the avant-garde artist collective OBERIU. The former wrote several excellent texts, including An Investigation of Horror, and in 1933–1934 recorded and preserved the Conversations between Kharms, Vvedensky, Oleinikov, Zabolotsky, Druskin, and Lipavsky himself. He went missing in action on the Leningrad Front on September 22, 1941. The latter left behind diaries he kept from 1926 to 1966, as well as philosophical works. During the siege winter of 1941, he transported the archives of the arrested Kharms from Mayakovsky Street to the Petrograd Side on a children’s sled, preserved them—along with Vvedensky’s manuscripts that later came into his possession—and in the 1960s made them available to certain literary scholars. He lived until the early 1980s. Neither Lipavsky nor Druskin considered themselves poets, but they left behind a number of poetic texts. It is these that we have published—thanks to literary scholar Valery Shubinsky.
