Princess Lee Radziwill with Thomas, her pug, photo by Henry Clarke, August 1960
Lee Radziwill (née Bouvier) is the younger sister of Jacqueline Kennedy. Lee's first marriage ended in divorce, and her second, in 1959, was to Prince Stanislas Radziwill, an ex-pat Polish nobleman. Henry Clarke photographed her at Turville Grange, her eighteenth -century country house in the Thames valley, with her pug, Thomas, who would accompany her to tea at the Ritz.
