Painter, born in London. She attended Putney School of Art, but economic necessity forced her to work for Prudential Assurance Company from 1915–22, when she studied at Regent Street Polytechnic School of Art. Married to the art and antiques dealer Jacob Mendelson, 1923–8, then married the painter David Bomberg. Painted with Bomberg widely overseas and became a founder-member of Borough Group, showing Archer Gallery, Arcade Gallery and elsewhere. Had a retrospective at Ben Uri Gallery in 1980, from which Tate Gallery bought a landscape, like much of her work strongly influenced by Bomberg, called Tajo Ronda. After Bomberg’s death Lilian, supported by her daughter Dinora Mendelson, also a member of the Borough Group, devoted years to promoting David Bomberg’s work.
