This paper is aimed at studying, and rectifying misunderstandings, of J. D. Salinger's works in the light of his daughter Margaret A. Salinger’s Dream Catcher: A Memoir. Salinger pursued Oriental ideas including Zen Buddhism and Vedanta theory. He studied and practiced Orientalism and Zen at the American Zen Center in the 1940s. Since Salinger lived a secret life for a long time without relationships with his family and others, we have had to read his works themselves without considering his biography. However, Margaret’s Memoir sheds light on the mystery of Salinger's writings and gives acute psychological insights to researchers. Through her Memoir, she makes readers reconsider Salinger’s works. Accordingly, her memoir has become one of the best books to reignite Salinger criticism. Thanks to this book, we can understand the Salinger myth in the papers published from the past until now, and studying his works can be vivid and strong again like in the 1960s. This new interest has been, called, “the second Salinger Industry.”
