Here we present an overview of his achievements in physics and its foundations which may serve as a guide to the bibliography (printed in this Festschrift) of his publications. An appraisal of Peter Mittelstaedt’s work in the philosophy of physics is given in a separate contribution by B. Falkenburg.</style></abstract><issue><style face="normal" font="default" size="100%">9-10</style></issue></record></records></xml>
