The influence of Hemingway's writings on American literature was considerable and continues today. Indeed, the influence of Hemingway's style was so widespread that it may be glimpsed in most contemporary fiction, as writers draw inspiration either from Hemingway himself or indirectly through writers who more consciously emulated Hemingway's style. In his own time, Hemingway affected writers within his modernist literary circle. James Joyce called "A Clean, Well Lighted Place" "one of the best stories ever written". Pulp fiction and "hard boiled" crime fiction (which flourished from the 1920s to the 1950s) often owed a strong debt to Hemingway. Hemingway's terse prose style--"Nick stood up. He was all right"-- is known to have inspired Bret Easton Ellis, Chuck Palahniuk, Douglas Coupland and many Generation X writers. Hemingway's style also influenced Jack Kerouac and other Beat Generation writers. J.D. Salinger is said to have wanted to be a great American short story writer in the same vein as Hemingway. Hunter S. Thompson often compared himself to Hemingway, and terse Hemingway-esque sentences can be found in his early novel, . Thompson's later suicide by gunshot to the head mirrored Hemingway's, although he used a .45 and not a shotgun. Hemingway also provided a role model to fellow author and hunter Robert Ruark, who is frequently referred to as "the poor man's Ernest Hemingway". In Latin American literature, Hemingway's impact can be seen in the work of fellow Nobel Prize winner Gabriel García Márquez. Beyond the more formal literature authors, popular novelist Elmore Leonard, who authored scores of Western and Crime genre novels, cites Hemingway as his preeminent influence and this is evident in his tightly written prose. Though he never claimed to write serious literature, he did say, "I learned by imitating Hemingway....until I realized that I didn't share his attitude about life. I didn't take myself or anything as seriously as he did."
