What do the pictures say-snapshots of a career.

What follows are snapshots of my career in chicken eyes, yeast and Rhodospirillum rubrum, castor beans, Escherichia coli and finally yeast again. In contrast, only a few of the failures that realistically make up a career are included. It is a tale of the generosity and influences of those who shaped what I am and what I learned in a wonderful profession. The science described is only that which I was lucky enough to do or was performed in my laboratory by those who really deserve the credit for any success that I've enjoyed. Not mentioned for lack of space are the critical contributions of many impressive investigators in the field of nitrogen-responsive regulation for no scientific investigation occurs in isolation. © FEMS 2017.
