me that chemistry was in a real bind because we had this very powerful molecular structure hypothesis that came from the cauldron of experimental physics. But everyone had their own dictionary - different people had a different idea of what a bond was. We were trying to do science with everyone using their own private dictionary. I decided that when I left, I would make it my goal to find the physical basis of chemistry.' Bader helped create the widely used software program, AIMPAC, that predicts the property of molecules based on the atoms in that molecule. Bader married Pamela Kozenof, a nurse from New Zealand, in 1958. They had three daughters, Carolyn, Kimberly and Suzanne. He had one grandson, Alexander.
