Secretary of State William Seward’s daughter and favorite child, Fanny Seward was an intelligent and sensitive young woman of twenty. She kept a detailed diary of all she saw in wartime Washington. On the night her father was attacked, she was sitting in the room with him and inadvertently put him in danger when she revealed to Lewis Powell where he lay. During the attack and afterwards, she screamed murder, scaring David Herold away from where he lurked in the shadows outside the Seward mansion.
