‘Tell me where all past years are’

  • David Alan Walker


This is about a young man who wished to go to sea like his father and finished up, instead, in photosynthesis. It describes how he served his apprenticeship in England and the United States and how he was then lucky enough to find himself in the laboratory of Robin Hill, one of the all-time greats in this field. It discusses some of the events that led, via mitochondria in castor beans and carboxylating enzymes in Crassulacean plants, to the isolation of fully functional chloroplasts and the manner in which the first polarographic measurements of CO2-dependent O2 evolution contributed to present understanding of the movement of molecules through the chloroplast envelope. It describes some of the problems with materials and apparatus which were commonplace forty years ago and reflects on the advantages of working in foreign places and the pleasures of becoming a member of a truly international community.
