It has been brought to my attention, by someone who actually follows Twitter, that "Sir David Butler, the father of psephology, or election science, died [on Tuesday] at the age of 98."
The person posting this was Michael Crick, who published a biography of Sir David a few years ago. I read that book and wrote here about it and the acknowledgment therein of my small contribution to it.
Crick writes in his tweets that Butler "promoted the word 'psephology' to describe the new study of election science." He writes carefully. Butler promoted the word, he didn't invent it. My contribution was to assist Crick's researchers in discovering who did invent it.
It was C.S. Lewis and the Inklings.
