Which American author wrote the novel 'Gravity's Rainbow'?

Thomas Pynchon wrote the novel “Gravity’s Rainbow.” Published in 1973 by Viking Press, it is an expansive American postmodern novel set mainly in Europe during the final months of World War II.

Its story revolves around V-2 rockets, military technology, paranoia, and the search for a mysterious device called the Schwarzgerät, or “black device.” The novel blends history, science, satire, songs, popular culture, and hundreds of interconnected characters, making it famous for its density and difficulty.

A common mix-up is confusing Pynchon with other major postwar American novelists such as William Gaddis or Don DeLillo. Pynchon is also associated with “The Crying of Lot 49” and “V.” “Gravity’s Rainbow” shared the 1974 National Book Award for Fiction, but it did not win the Pulitzer Prize for Fiction: that prize was not awarded in 1974 after the advisory board rejected the jury’s recommendation.
