Gerard, Duke of Lorraine (born c. 1030)

Gerard, also known as Gerard the Wonderful, was a Lotharingian nobleman. He was the count of Metz and Châtenois from 1047 to 1048, when his brother Duke Adalbert resigned them to him upon his becoming the Duke of Upper Lorraine. On Adalbert's death the next year, Gerard became duke, a position that he held until his death. In contemporary documents, he is called Gerard of Alsace, Gerard of Chatenoy, or Gerard of Flanders.
