Thanks for the link Ishbel! I love what it said about the Historical Experience:
he Historical Experience at Benjamin Franklin House will stand alone among London attractions in its 'museum as theatre' approach, setting a new standard for historical interpretation.
The main character in the Historical Experience is Polly Hewson, daughter of Franklin's landlady who became a 'second daughter' to Franklin. Accompanied by Polly, who will assume visitors are there to see Franklin on his last night in London when he had to leave or risk arrest, the visitor will experience a sense of the complexity of the man and the times in which he lived: food, health, botany, and daily living in the basement kitchen; social and personal relationships, musical inventions and political tension on the ground floor; scientific work, political triumphs and woes, and a hurried return to America in the face of the looming War of Independence on the first floor.
