Robert Lenkiewicz (1941–2002) worked within ‘Projects’: large-scale exhibitions of paintings and research notes related to sociological issues. His themes – vagrancy, mental handicap, old age, suicide, death – sought to illuminate the lives of those he called “the invisible people”. In other Projects –- with themes of falling in love, jealousy, orgasm, and obsessive attraction – Lenkiewicz looked at “addictive behaviour” of various kinds. Observing that intense attractions tended to make fanatics of us all, he concluded that the origins of obsessional relationships and fanatical belief systems shared a physiological cause.
