Eric Breuer is a Swiss archaeologist and historian.
He studied archaeology and history at the Universities of Munich, Vienna, Fribourg and Basel. He discovered the Roman vicus of Eriskirch (Lake Constance), and conducted widespread research on early Medieval archaeology, archaeology of Roman provinces, Avar archaeology, and Mediterranean history. His main interest was the relative chronology of Roman and early medieval times.
Contrary to early eastern European archaeologists, like I. Kovrig and others, B. favoured the idea, that changes in ornaments and manufacturing of belts are not signs of new arriving ethnic groups in the Carpathian basin, but simply changes of fashion and lifetime of certain processes of production of goods - and not ethnic conclusions. As a result chronological horizons get at Breuer's work the meaning of starting, increasing, decline and end of fabrications of certain types of small findings.
