Heimerad was a German priest and hermit who lived from approximately 970 to 1019. Born to parents of unfree status in Messkirch, he traveled extensively through Italy, Germany, and Palestine. Although he attempted to live as a monk at Hersfeld Abbey, he was eventually expelled following a disagreement regarding monastic attire. After being rejected by other monasteries, he established a hermitage on the Hasunger Berg, where he spent his later years as a traveling preacher.
