Nancy Clara Cunard (10 March 1896 – 17 March 1965) was a British writer, heiress and political activist. She was born into the British upper class, and devoted much of her life to fighting racism and fascism. She became a muse to some of the 20th century's most distinguished writers and artists, including Wyndham Lewis, Aldous Huxley, Tristan Tzara, Ezra Pound and Louis Aragon—who were among her lovers—as well as Ernest Hemingway, James Joyce, Constantin Brâncuși, Langston Hughes, Man Ray and William Carlos Williams. MI5 documents reveal that she was involved with Indian socialist leader V. K. Krishna Menon.
