Thanks for this comment. I recently discovered that the inventor of PCM, Alec Reeves, was also involved in the development Oboe system for guidance of bombers. https://en.wikipedia.org/wiki/Alec_Reeves https://en.wikipedia.org/wiki/Alec_Reeves (the offsite reference pages are particularly good) I get the sense that he was much less of a mover and shaker than either Blackett or Zuckerman. By the same token, I wonder if they have been idolized a bit (even though I had never heard of them, and their names are clearly not heard very often these days.)
