Robert, called "The Magnificent" for his love of finery, and also called "The Devil" was the son of Duke Richard II of Normandy and Judith, daughter of Conan I, Duke of Brittany. When his father died, his elder brother Richard succeeded, whilst he became Count of Hiémois. When Richard died a year later, there were great suspicions that Robert had Richard murdered, hence his other nickname, "Robert le diable" (the devil). Wikipedia
