Bush, have become president in their own right. Presidential children have been studied individually and as a class. As individuals they are more often notable in their own right than most individuals: They disproportionately circulate among political and social leaders and the wealthier classes, and they are more likely to be scrutinized as part of celebrity culture. Additionally, as individuals they frequently have significant influence on other family members. For instance, a child may have had a significant influence on the child's parent: acting as a sounding board, or having behavioral issues that affected the parent's beliefs or performance. John Scott Harrison is the only person to be both a child of a U.S. president and a parent of another U.S. president, being a son of William Henry Harrison and the father of Benjamin Harrison. As a class, the children of presidents have also occasioned significant study.
