The mathematician John Venn introduced Venn diagrams around 1880. From the internet I see that Kurt Lewin only got going in psychology in the 1920s, so I can't quite see how this fits the notion of certain perspectives in psychology coinciding with "historical and popular events". And I can't recall that Venn diagrams play any role in field physics. Allen Esterson Former lecturer, Science Department Southwark College, London http://www.esterson.org ---
