Bob and Marilyn were good friends when we lived in Bogota, Colombia, in 1964,. They took me and my new daughter in when I was alone. In Medellin, in 1967, they hosted my husband, child and I during a difficult summer. Both Marilyn and Bob were loving, caring people, a comfort to be with, and an inspiration in their dedication to their work and vision. Jamie, Margaret, and Catherine Santina, I am sorry for your loss.
