Ivan Vasilievich Gruzinov (1893-1942) - a writer from a long list of forgotten names. The common-law husband of the futurist poetess Nina Khabias and a faithful friend of Sergei Yesenin; a poet who survived the school of symbolism, the excitement of futurism and the circus school of imagism; in many ways close to the monastery of the "new peasant merchant," but always original. A subtle critic, an attentive literary critic and a vivid memoirist, Ivan Gruzinov is the author of the famous treatise-manifesto "Basic Imagism," memoirs about S. Yesenin and V. Mayakovsky. The book includes texts published in newspapers, magazines, collective collections and original editions of the early twentieth century, as well as new archival searches.
