Here, in alphabetical order, are the faces of those that we believe to be the 80 most influential people (from the 13th century to date) who have critically shaped thinking about problem solving and organisational development. We have divided these first metre pioneers into four groups. Our apologies for omissions - just tell us who you think should be added - or perhaps who you think should be relegated.
