Painter, highly versatile printmaker and teacher, Heindorff attended art college and University of Braunschweig, in Germany, 1970–4. He gained a German National Scholarship, 1972–6, and a DAAD Scholarship for London, 1976–7, attending Royal College of Art, 1975–7. Heindorff was at home in various media and styles, although over the years he edged away from figuration to abstraction. He won an award at John Moores Exhibition in Liverpool in 1976, a few years later gaining the Schmidt-Rottluff Prize and the Villa Massimo Prize, in Rome. A retrospective of his work covering the decade from 1977 was held at Northern Centre for Contemporary Arts in 1987. For many years his pictures were handled by Bernard Jacobson in London and New York. Arts Council holds.
