I knew Elsa many years ago when I lived in Palo Alto. We worked together at Eastman Kodak. I visited her at her home in Portola Valley many times and always enjoyed her company even though she was twice my age. Elsa was gracious, funny and very intelligent. We wrote for a while but as happens so often, you lose touch after a while. But I will never forget Elsa, and I look forward to seeing her again on the other side.
