Remembering David B. Knaff (1941–2016)
David Knaff began his scientific career in the Department of Cell Physiology at the University of California, Berkeley. At Berkeley, he worked on chloroplast electron carriers such as the cytochromes and plastocyanin and applied redox potentiometry to characterize these carriers in situ. He moved to Texas Tech University where he made major contributions in the study of ferredoxin-mediated reactions with chloroplast enzymes, most notably nitrite reductase.

I would like to thank all David’s friends and colleagues who contributed to this Tribute. Their timely response to my requests made my task much easier. In some cases, I did some minor editing of their contributions, and I hope they will forgive me for taking this liberty.
