Forty years of research on the assembly and infection process of bacteriophage.

This short biographical note was written as part of the lead-in material for a festschrift kindly organized for me on the occasion of my 70th birthday. The collection of articles assembled in this issue range within the spectrum of the topics covered in the special issue 'Multiscale structural biology-biophysical principles and practice ranging from biomolecules to bionanomachines.' Here I describe some of the high points of my 40 years of research science conducted in the USA, Switzerland and Japan. I also use this opportunity to express my sincerest thanks to my former colleagues and the very many contributors who so kindly contributed to this special issue.
