Figurative artist, born in London, who studied at Chelsea School of Art, 1979–80, and at Central St Martins School of Art 1980–1 and 1986–9. Moved to New York in 1991, where for two years she operated Trial Balloon, an alternative women-only gallery, in her studio loft. Tyson had sell-out solo shows, there in 1993 and elsewhere, producing works compared by some critics to those of Hans Bellmer, Francis Bacon and the Surrealists, with a fluid handling of paint and fine draughtsmanship. Her figures included biological mutations and could be erotic and disturbing. Group exhibitions included Whitechapel Open, at Whitechapel Art Gallery, from 1988; Milch Gallery, 1990, where Tyson showed a range of hybrid creatures made from sectional plaster casts of toy pets; Urban Analysis, Barbara Braathen Gallery, New York, 1993; Identity Crisis, The Puffin Foundation, New York, 1994; and Revealing Desire, Cristinerose Gallery, and Human/Nature, The New Museum of Contemporary Art, both New York in 1995.
