What influenced J. D. Salinger's writing specifically?
J. D. Salinger seems to have been an extreme introvert. For many years he lived, much of the time alone, in a house surrounded by a high wall. He refused to give interviews, although he was famous and sought after. He avoided people as much as possible. He had few people he associated with. Writing for Salinger must have been a form of escape from the loneliness that would be inevitable for a person with such a lifestyle. His writing gives strong clues as to why he avoided people. As a hypersensitive, highly intelligent introvert, most people grated on his nerves.
The Catcher in the Rye has been extremely popular with young readers for many decades. Anyone who likes this novel should read Salinger's other published books. One is a collection of short stories titled Nine Stories. Another book contains two long stories about a brother and sister. It is titled Franny and Zooey (1961). A third book is titled Raise High the Roofbeam, Carpenters (1963). A fourth is Seymour: An Introduction (1963).
Salinger stopped publishing many years ago at the height of his fame. His admirers kept hoping that he would come out with more stories or books, but he remained mysteriously silent. Hapworth 16, 1924, a book published in 1997, was not a new work; it was published in the New Yorker magazine in 1965.
