Osip Emilyevich Mandelstam (; – 27 December 1938) was a Russian poet and essayist who lived in Russia during and after its revolution and the rise of the
Soviet Union and husband of
Nadezhda Mandelstam. He was one of the foremost members of the
Acmeist school of poets. He was arrested by
Joseph Stalin's government during the repression of the 1930s and sent into internal exile with his wife
Nadezhda. Given a reprieve of sorts, they moved to
Voronezh in southwestern Russia. In 1938 Mandelstam was arrested again and sentenced to a camp in
Siberia. He died that year at a transit camp.
