Question: Extract all the authors named in this paragraph on the controversies about Nobel laureate selections
Evidence: From 1901 to 1912, the committee, headed by the conservative Carl David af Wirsén, weighed the literary quality of a work against its contribution towards humanity's struggle 'toward the ideal'. Leo Tolstoy, Henrik Ibsen, Émile Zola, and Mark Twain were rejected in favour of authors little read today.

The first prize in 1901, awarded to the French poet Sully Prudhomme, was heavily criticised. Many believed that the acclaimed Russian author Tolstoy should have been awarded the first Nobel prize in literature.

The choice of philosopher Rudolf Eucken as Nobel laureate in 1908 is widely considered to be one of the worst mistakes in the history of the Nobel Prize in Literature. The main candidates for the prize that year were poet Algernon Swinburne and author Selma Lagerlöf, but the Academy were divided between the candidates and, as a compromise, Eucken, representative of the Academy's interpretation of Nobel's "ideal direction", was launched as an alternative candidate that could be agreed upon.

The choice of Swedish writer Selma Lagerlöf as Nobel laureate in 1909 (for the "lofty idealism, vivid imagination and spiritual perception that characterizes her writings") followed fierce debate because of her writing style and subject matter, which broke literary decorums of the time.

During World War I and its immediate aftermath, the committee adopted a policy of neutrality, favouring writers from non-combatant countries. The pacifistic author Romain Rolland was awarded the prize for 1915. Other years during the war Scandinavian writers were favoured, or the award was postponed.

In 1931 the prize was awarded posthumously to the poet and former permanent secretary of the Swedish Academy Erik Axel Karlfeldt, who had died earlier that year. The prize was controversial not just because it was the first and only time the Nobel Prize in Literature was awarded posthumously, but because the Academy had previously awarded two other Swedish writers of the same literary era, Selma Lagerlöf in 1909 and Verner von Heidenstam in 1916. Internationally it was heavily criticised as few had heard of Karlfeldt.

The Nobel Prize awarded to Pearl Buck in 1938 is one of the most criticised in the history of the prize. The Academy awarded Buck "for her rich and truly epic descriptions of peasant life in China and for her biographical masterpieces", referring to acclaimed and popular books published only a few years earlier. But her later work is generally not considered to be of the literary standard of a Nobel laureate.

John Steinbeck received the 1962 Nobel Prize in Literature. The selection was heavily criticised, and described as "one of the Academy's biggest mistakes" in one Swedish newspaper. The New York Times asked why the Nobel committee gave the award to an author whose "limited talent is, in his best books, watered down by tenth-rate philosophising", adding, "we think it interesting that the laurel was not awarded to a writer ... whose significance, influence and sheer body of work had already made a more profound impression on the literature of our age".

In 1964, Jean-Paul Sartre was awarded the Nobel Prize in Literature, but he wrote declining it, stating that "It is not the same thing if I sign Jean-Paul Sartre or if I sign Jean-Paul Sartre, Nobel Prize laureate. A writer must refuse to allow himself to be transformed into an institution, even if it takes place in the most honorable form." Nevertheless he was awarded the prize.

Soviet dissident writer Aleksandr Solzhenitsyn, the 1970 prize laureate, did not attend the Nobel Prize ceremony in Stockholm for fear that the USSR would prevent his return afterwards (his works there were circulated in samizdat—clandestine form). After the Swedish government refused to honour Solzhenitsyn with a public award ceremony and lecture at its Moscow embassy, Solzhenitsyn refused the award altogether, commenting that the conditions set by the Swedes (who preferred a private ceremony) were "an insult to the Nobel Prize itself." Solzhenitsyn did not accept the award and prize money until 10 December 1974, after he was deported from the Soviet Union. Within the Swedish Academy, member Artur Lundkvist had argued that the Nobel Prize in Literature should not become a political prize and questioned the artistic value of Solzhenitsyn's work.

In 1974, Graham Greene, Vladimir Nabokov, and Saul Bellow were believed to be likely candidates for the prize but the Academy decided on a joint award for Swedish authors Eyvind Johnson and Harry Martinson, both members of the Swedish Academy at the time, and unknown outside their home country. Bellow received the Nobel Prize in Literature in 1976; neither Greene nor Nabokov was awarded it.
