Great to see Arthur Lewis as a Google Doodle today. I often reference him to new faculty: “I got into the history of the world economy because Frederick Hayek, then Acting Chairman of LSE Dept of Economics suggested I teach a course on “what happened between the wars” ...
... to give concreteness to the massive doses of trade cycle theory which then dominated the curriculum. I replied to Hayek that I did not know what happened between the wars; to which he replied that *the best way of learning a subject was to teach it*.” https://www.nobelprize.org/prizes/economic-sciences/1979/lewis/biographical/
Important when teaching students who want to learn Economics without Maths being their opening focus.
One more thing on Arthur Lewis: the double-Saint Lucia link to the Nobel with Derek Walcott. When they were growing up, the population of Castries would have been only a few thousand. http://saintluciaconsulateny.org/our-nobel-laureates/
