Ezra Pound and William Carlos Williams, two towering figures in American poetry, began their lifelong, and often contentious, friendship as students at the University of Pennsylvania. Their correspondence ran from 1907, the year Pound took up his virtually permanent residence in Europe, until Williams' death in 1963. The letters contribute an unparalleled documentary record of modern culture - a wealth of information about the lives and works of the two poets themselves; the literary and political movements in which they became involved and the impact of public events upon the arts; the activities of other writers and artists; and the world of small presses and little magazines that nourished the growth of modernism.
