Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. I feel that the responsibility for the success of the present book rests in some measure on my shoulders since I urged its publication both with the author and publisher. At For many years it had been my earnest desire that some day I might be permitted to join forces with three old friends and fellow students for the purpose of jointly editing an exhaustive and historical research into the principles Of that method and school of violin playing from which we four had been graduated. These three distinguished artists are Franz Kneisel (of illustrious chamber music fame), Felix Winternitz and Eugene Gruenberg, the last two, violin professors Of great repute at the New England Conservatory in Boston.
