by Robert Olby (2009). Well researched and documented, 500 page long, biography of Francis’ life, the intellectual giant who dominated biology in the 20. century like none else. The penultimate chapter From the searchlight to the soul covers Francis’ and my joint work on the neuronal basis of consciousness from the mid 1980s until his death in 2004. All in all, we wrote and published two dozen joint papers and book chapters, and one book each on these topics.
