By the time of Hesse's death in 1962, his works were still relatively little read in the United States, despite his status as a Nobel laureate. A memorial published in "The New York Times" went so far as to claim that Hesse's works were largely "inaccessible" to American readers. The situation changed in the mid-1960s, when Hesse's works suddenly became bestsellers in the United States. The revival in popularity of Hesse's works has been credited to their association with some of the popular themes of the 1960s counterculture (or hippie) movement. In particular, the quest-for-enlightenment theme of "Siddhartha", "Journey to the East", and "Narcissus and Goldmund" resonated with those espousing counter-cultural ideals. The "magic theatre" sequences in "Steppenwolf" were interpreted by some as drug-induced psychedelia although there is no evidence that Hesse ever took psychedelic drugs or recommended their use. To a large part, the Hesse boom in the United States can be traced back to enthusiastic writings by two influential counter-culture figures: Colin Wilson and Timothy Leary. From the United States, the Hesse renaissance spread to other parts of the world and even back to Germany: more than 800,000 copies were sold in the German-speaking world from 1972 to 1973. In a space of just a few years, Hesse became the most widely read and translated European author of the 20th century. Hesse was especially popular among young readers, a tendency which continues today.
