I was asked recently why Jacques Monod did not followup on his early work on bacterial growth. Instead, he happily veered in a different direction and went on to become one of the fathers of Molecular Biology. Together with François Jacob, he proposed the operon model and other key breakthroughs on the regulation of gene expression. The Nobel prize followed.
Specifically, why did Monod not go on to study how bacteria respond globally to changes in growth conditions? The questioner had in mind why Monod did not make the simple measurements that became the basis for the Copenhagen School of Growth Physiology (aka the Maaløe School). Having lived through those times, I should be able to conjure up a response.
