Quote from : The Cambridge Companion to Jewish American Literature Book

The most celebrated American author of the twentieth century, Bellow objected during the first part of his career to being designated a “Jewish writer, ” but it was he who demonstrated how a Jewish voice could speak for an integrated America. With Bellow, Jewishness moved in from the immigrant margins to become a new form of American regionalism. Yet he did not have to write about Jews in order to write as a Jew. Bellow's curious mingling of laughter and trembling is particularly manifest in his novel Henderson the Rain King, that follows an archetypal Protestant American into mythic Africa. Bellow not only influenced and paved the way for other American Jewish writers like Philip Roth and Cynthia Ozick, but naturalized the immigrant voice: the American novel came to seem freshly authentic when it spoke in the voice of one of its discernible minorities.
