Richard David Ellmann was an American literary critic and biographer of the Irish writers James Joyce, Oscar Wilde, and William Butler Yeats. He won the U.S. National Book Award for Nonfiction for James Joyce (1959), one of the most acclaimed literary biographies of the 20th century. Its 1982 revised edition won James Tait Black Memorial Prize. Ellmann was a liberal humanist, and his academic work focuses on the major modernist writers of the 20th century.
I got this book from a clearance table at a bookstore many a year ago, when I was in the heyday of my James Joyce mania. Ellmann is a foremost Joyce scholar and I soaked up these essays like a sponge, helping me to understand Joyce (and Yeats and some other favorites he writes about).
