A Columbia graduate student and his adviser have authenticated the student’s discovery of an unknown manuscript of a 1941 novel by Claude McKay, a leading Harlem Renaissance writer and author of the first novel by a black American to become a best seller.

The manuscript, “Amiable With Big Teeth: A Novel of the Love Affair Between the Communists and the Poor Black Sheep of Harlem,” was discovered in a previously untouched university archive and offers an unusual window on the ideas and events (like Mussolini’s invasion of Ethiopia) that animated Harlem on the cusp of World War II. The two scholars have received permission from the McKay estate to publish the novel, a satire set in 1936, with an introduction about how it was found and its provenance verified.

McKay, a Jamaican-born writer and political activist who died in 1948, at 58 (though some biographies say 57), influenced a generation of black writers, including Langston Hughes. His work includes the 1919 protest poem “If We Must Die,” (quoted by Winston Churchill) and “Harlem Shadows,” a 1922 poetry collection that some critics say ushered in the Harlem Renaissance. He also wrote the 1928 best-selling novel “Home to Harlem.” But his last published fiction during his lifetime was the 1933 novel “Banana Bottom.”
