A Personal Perspective: My Four Encounters with John Kendrew.

By celebrating the 100th anniversary of John Kendrew's birth in 1917, the Journal of Molecular Biology recognizes his seminal contributions to science in general and structural biology in particular. John was first to use X-ray diffraction to solve the 3-dimensional structure of a protein, sperm-whale myoglobin, worthy of a Nobel Prize in Chemistry in 1962. John was the Founder and first Editor-in-Chief of the Journal of Molecular Biology, Deputy Chairman of the Laboratory of Molecular Biology and Head of its Division of Structural Studies, a Founder of the European Molecular Biology Organization, first Director-General of the European Molecular Biology Laboratory, and 33rd President of St. John's College, Oxford. In this personal perspective I relate how I came to know John as his postdoctoral fellow at the Laboratory of Molecular Biology in 1967 and as his biographer 45 years later.
