Learn about the Beatles song 'Taxman,' which was inspired by Britain's tax structure

The poem behind 'Strange Fruit'

"Bitter Fruit" was written by Abel Meeropol, a teacher, under the pseudonym Lewis Allen, after seeing a photograph of a lynching.

The painting accompanied an article about the inequities of the justice system, which is why its title often includes the parenthetical "(Southern Justice)."

The Beatles' visit with Maharishi Mahesh Yogi helped inspire Western interest in Eastern spirituality

The Fab Four met with the guru—the creator of Transcendental Meditation—in 1968 in Rishikesh, India.

Kurt Vonnegut's satire embraced dark humor

Books like "Cat’s Cradle" and "Slaughterhouse Five" satirized the international appetite for war, which the 20th-century writer found both horrifying and hilarious. It’s a combination that some called “gallows humor,” a classification Vonnegut himself remembered Sigmund Freud describing. “One of the examples Freud gives is a man about to be hanged,” Vonnegut once recalled, “and the hangman says, ‘Do you have anything to say?’ The condemned man replies, ‘Not at this time.’”
