Wow!  Very interesting, Philippa.  I assume you do know that Seebohm Rowntree became a big fan of Mary Parker Follett, brought her to the UK to give talks to businessmen.  Lyndall Urwick, co-editor of Dynamic Administration, worked for Rowntree at that time. While at the Rowntree Foundation I came across some of the wonderful thinking and work of the British Quaker chocolate makers.  Very fascinating. An influence on Follett, I suspect.  Keep us posted of your discoveries!  I think it is to Lyndall Urwick (who admits he lifted some of Follett's works from Dame Katharine Furse, and I think that Dame Katharine made it possible for him to do so, but this is all my private speculation) that we owe thanks for knowing what we do about Follett.  I met his widow in Australia in the early 1990s.
