An Album of Presidents and Their Children

Ulysses S. Grant
Three of Grant's four children gathered for this multigenerational portrait taken around 1880: his only daughter Nellie, far left, his youngest son Jesse (behind her) and the eldest, Frederick, standing toward the right, with hand on hip. Jesse was an author, engineer and world traveler. Frederick served with his father on the major battlefields of the Civil War. Nellie was married twice, the first time to a dissolute diplomat whose death left her a wealthy woman.
