Dear Prof Kim,

I thought you may like a copy of the attached photo. You are welcome to place it on your web site. The original belongs to me (I picked it up many years ago in a Parisian antique shop). I believe the lady in the picture is Irene Joliot-Curie, Marie Curie's daughter. I presume the photo was taken outside Einstein's house on Mercer Street in Princeton.

Best wishes,
John Webb

Here is a Wikepedia article about Irene Joliet-Curie.
