Context paragraphs:
Ivan Elagin (poet): Ivan Elagin (December 1, 1918 – February 8, 1987; Ukrainian: Иван Елагин , Russian: Иван Венедиктович Елагин , real name Ivan Matveyev, was a Russian émigré poet born in Vladivostok.  He was the husband of poet Olga Anstei (Ukrainian: Ольга Анстей ), best remembered for writing about the Holocaust.  His "Kirillovskie iary" (another name for Babi Yar) written in 1943, was one of the first-ever literary works on the subject of 1941 massacre of Ukrainian Jews in Kiev.

Lev Ozerov: Lev Ozerov (Russian: Лев Адольфович Озеров ) (August 10/23, 1914 – March 18, 1996) was a Jewish-Ukrainian Soviet poet born in Kiev.  Ozerov was the professor of Literary Translation at the Literary Institute until his death.  He was one of the first Jewish authors who wrote poems about Babi Yar along with Liudmila Titova and Leonid Pervomayskiy.  He visited that place of martyrology of Ukrainian Jews in Kiev immediately after the liberation.  His famous epic "Babi Yar" first appeared in the "октябрь" ("October") () magazine March–April 1946 issue.  Ozerov served as poetry editor of "October" ("октябрь") in 1946–1948, one of the more important literary publications at the time.

Symphony No. 12 (Shostakovich): Dmitri Shostakovich composed his Symphony No. 12 in D minor, Op. 112, subtitled "The Year of 1917", in 1961, dedicating it to the memory of Vladimir Lenin, leader of the Bolshevik Revolution, as he did for his Symphony No. 2.  The symphony was premiered that October by the Leningrad Philharmonic Orchestra under conductor Yevgeny Mravinsky.  This was also the last Shostakovich symphony which Mravinsky premiered; his refusal to give the first performance of the Thirteenth Symphony, "Babi Yar", caused a permanent strain in their working relationship.

Symphony No. 13 (Shostakovich): The Symphony No. 13 in B-flat minor (Op. 113, subtitled "Babi Yar") by Dmitri Shostakovich was completed on July 20, 1962 and first performed in Moscow on 18 December 1962 by the Moscow Philharmonic Orchestra and the basses of the Republican State and Gnessin Institute Choirs, under Kirill Kondrashin (after Yevgeny Mravinsky refused to conduct the work).  The soloist was Vitali Gromadsky.  This work has been variously called a song cycle and a choral symphony since the composer included settings of poems by Yevgeny Yevtushenko that concerned the World War II Babi Yar massacre and other topics.  The five poems Shostakovich set to music (one poem per movement) are earthily vernacular and cover every aspect of Soviet life.

Babi Yar in poetry: Poems about Babi Yar commemorate the massacres committed by the Nazi "Einsatzgruppe" during World War II at Babi Yar, in a ravine located within the present-day Ukrainian capital of Kiev.

Subsequent massacres also included Ukrainians and Poles.  The Babi Yar massacre is considered to be "the largest single massacre in the history of the Holocaust".  Executions of Jews, Ukrainians, Gypsies and others continued in Babi Yar throughout the period of the Nazi occupation of Kiev, ending with the beginning of the Battle of Kiev (1943), totalling up to 120,000 victims.

Babi Yar: A Document in the Form of a Novel: Babi Yar: A Document in the Form of a Novel (Russian: Бабий яр.  Роман-документ ) is an internationally acclaimed documentary novel by Anatoly Kuznetsov about the Babi Yar massacre.

Nikolaev massacre: The Nikolaev Massacre was a massacre which resulted in the deaths of 35,782 Soviet citizens, most of whom were Jews, during World War II, on September 16–30, 1941.  It took place in and around the city of Mykolaiv (also known as Nikolaev) and the neighboring city of Kherson in (current) southern Ukraine (then USSR).  The massacre was carried out by German troops of Einsatzgruppe D under the command of Otto Ohlendorf, who was later convicted at the Einsatzgruppen trial of the Nuremberg Trials and was sentenced to death by hanging.  The killings were committed by many of the same troops who carried out the massacre at Babi Yar, and the victims were counted and described in an Einsatzgruppen document dated October 2, 1941 as "Jews and Communists".  This document was entered into evidence at the Nuremberg Trials as NO-3137.
