At the end of 1947, beginning of 1948, Linus Pauling came to Oxford as Visiting Professor. The Nature of the Chemical Bond was the most influential book in my scientific education, and I had a tremendous hero-worship admiration for the man. I hstened to his lectures spellbound, and, through Dorothy, I actually met the great man. That summer, partly through Verner Schomaker s initiative, I got an offer to come to Caltech as a Research Fellow, and there was no hesitation. 

Mostly in collaboration with Kenneth Trueblood and Verner Schomaker, I also worked for a long time on the motion of atoms and molecules... 

The displacements of atoms may take several forms (Figure 13.2). These have been described by Jack Dunitz, Verner Schomaker, and Kenneth N. Trueblood as follows The perfectly ordered crystal would have every atom firmly fixed to its own perfectly defined site in each unit cell for the entire period of observation. There are, however, various types of disorder from unit cell to unit cell. If the atom jumps to a different site, that is one kind of disorder [a mixture of static and dynamic disorder ] if it moves to and fro, that is another kind of disorder [ dynamic disorder] if it is forever in one site in a certain unit cell and in a different site in another cell, that is still another kind [static disorder]. Each of these types of vibrations, displacements, and disorder has somewhat similar effects on the intensities of Bragg reflections the effect they have in common is that they reduce these intensities by an amount that increases with increasing scattering angle, 26, as shown in Figure 13.1.

The author is indebted to Professor Linus Pauling and to Professor Verner Schomaker for many helpful criticisms and suggestions.
