From the reviews/Aus den Besprechungen: "...Für den an der Geschichte der Zahlentheorie interessierten Mathematikhistoriker ist das Buch mindestens in zweierlei Hinsicht lesenswert. Zum einen enthält der textual content eine ganze Reihe von historischen Hinweisen, zum anderen legt der Autor sehr großen Wert auf eine möglichst allseitige Motivierung seiner Darlegungen und versucht dazu, insbesondere den wichtigen historischen Schritten auf dem Weg zur Klassenkörpertheorie Rechnung zu tragen. Die Anhänge von O. Taussky bilden eine wertvolle Ergänzung des Buches. ARTINs Vorlesungen von 1932, deren Übersetzung auf einem Manuskript basiert, das die Autorin 1932 selbst aus ihrer Vorlesungsnachschrift erarbeitete und von H. HASSE durchgesehen sowie mit Hinweisen versehen wurde, dürfte für Mathematiker und Mathematikhistoriker gleichermaßen von Interesse sein..."
