One can distinguish three broad periods in the evolution of Biometrika. The first was up to 1914; important developments in statistical methods were reported but the great majority of the space was taken up with detailed analyses of empirical data from a remarkably wide range of subject areas. The period from the end of the Great War up to K.P.'s death was by and large less interesting for reasons that are probably clear. With K.P.'s son Egon becoming editor, the journal changed to being a mainstream journal of statistical theory and method, evolving as the subject evolved but aiming always to keep some balance between theoretical interest and actual or potential application.
To celebrate the Centenary the current editor, D.M.Titterington, has commissioned six special papers reviewing the contribution of the journal to some of the main areas of statistics. These papers, together with a brief historical introduction, are included in the first part of the 2001 volume. The authors are R.A.Bailey & A.C.Atkinson, A.C.Davison, P.Hall, D.Oakes, T.M.F.Smith and H.Tong. These papers plus reprints of 10 important early papers will be published later by Oxford University Press as a separate book.
