Abstract
We present here the life and the work of Paul A. Castelfranco (1921–2021), a very special person who was not only a top chemist of chlorophyll biosynthesis, but also made major contributions on fatty acid oxidation, acetate metabolism and cellular organization. He led an extraordinary and exemplary life as a human being. We present here both his personal life as well as his scientific life, which is followed by reminiscences by William Breidenbach, Kevin Smith, Alan Stemler, Ann Castelfranco, and John Castelfranco. As the subtitle of this Tribute implies, till the end Paul was a scientist par excellence, an intellectual with unlimited curiosity, a humanist, and a man of enduring religious faith. We all miss him dearly.
