Black and white photo of Cécile from the first tweet. She is wearing a floral print shirt and smiling at the camera. A blackboard and file cabinet are visible in the background behind her. I think one of the drawers just visible at the left edge of the photo is the one with her "problem bank" of thesis-level problems.

   Cécile worked on whatever she found interesting, and she was famous for having a seemingly inexhaustible supply of thesis-level problems for curious students.

   She had a "problem drawer" in one of her file cabinets — it may very well have been one of the drawers visible in this photo from the first tweet. When Cécile met with a new student, she'd pull something from the drawer for them to work on.
