Ada Leverson , nee Beddington, was a British writer, now known as a novelist.
She began writing during the 1890s, as a contributor to Black and White, Punch, and The Yellow Book. She was a loyal friend to Oscar Wilde, who called her Sphinx; in the 1997 film Wilde she is played by Zoe Wanamaker. She was a wit, and a friend of Max Beerbohm; her writing has been compared to Beerbohm's, and the stories of Saki.
