Portrait sculptor, painter and writer. Born in London, she was educated at the Convent of the Assumption, Paris, and in Darmstadt, Germany. Studied art at the Royal College of Art and with John Tweed. After the death of her husband a week after the birth of her son Richard, in 1915, Sheridan spurred a career as a professional sculptor by commissioning her own portrait from Jacob Epstein and watching him work. Exhibited at the RA and overseas. She produced many portrait busts of famous people, including Lord Oxford and Asquith for the Oxford Union, Lord Birkenhead, Winston Churchill, Mahatma Gandhi and Lenin and Trotsky, for the Soviet government. Sheridan’s visit to Communist Russia led to her being briefly ostracised, so she went to America, was a journalist on the New York World, travelled to the west coast and became friendly with Charlie Chaplin.
