Johns Hopkins loved his cousin, but couldn’t marry her because they were Quakers. Instead they married no one and joined in a lifetime platonic partnership. With no heirs, the successful J. Hopkins designated his entire fortune to found Johns Hopkins University and Hospital. Every year the University sends a celebratory contingent to Hopkins’ grave at Green Mount Cemetery to honor his memory. So while a different Green Mount memorial promises eternal life through the memories of loved ones, Hopkins had better success by leaving no one.
