Leonora Christina, Countess Ulfeldt, born "Countess Leonora Christina Christiansdatter" til Slesvig og Holsten, was the daughter of King Christian IV of Denmark and wife of Steward of the Realm, traitor Count Corfitz Ulfeldt. Renowned in Denmark since the 19th century for her posthumously published autobiography, Jammers Minde, written secretly during two decades of solitary confinement in a royal dungeon, her intimate version of the major events she witnessed in Europe's history, interwoven with ruminations on her woes as a political prisoner, still commands popular interest, scholarly respect, and has virtually become the stuff of legend as retold and enlivened in Danish literature and art.

Leonte Răutu was a Bessarabian-born Romanian communist activist and propagandist, who served as deputy prime minister in 1969–1972. He was chief ideologist of the Romanian Communist Party during the rule of Gheorghe Gheorghiu-Dej, and one of his country's few high-ranking communists to have studied Marxism from the source. Răutu was of Jewish origin, though he embraced atheism and anti-Zionism. His adventurous youth, with two prison terms served for illegal political activity, culminated in his self-exile to the Soviet Union, where he spent the larger part of World War II. Specializing in agitprop and becoming friends with communist militant Ana Pauker, he joined the Romanian section of Radio Moscow.
