Kathleen Esther Garman, Lady Epstein (15 May 1901 – August 1979) was the third of the seven Garman sisters, who were high-profile members of artistic circles in mid-20th century London, renowned for their beauty and scandalous behaviour.
She was the model and longtime mistress of British/American sculptor Jacob Epstein, and eventually his second wife.
They met in 1921 and immediately began a relationship that lasted until Epstein's death and produced three of Epstein's five children.
Their daughter, Kitty Garman, was the first wife of Lucian Freud; their son was the artist Theodore Garman.
