I'm probably the Mooers' expert here on HN. Mooers worked at the Naval Ordnance Lab headed by John Atanasoff, of Atanasoff-Berry computer fame. He was one of the very first people working on digital computers. (Eg, see https://cacm.acm.org/magazines/2020/1/241712-von-neumann-thought-turings-universal-machine-was-simple-and-neat/fulltext https://cacm.acm.org/magazines/2020/1/241712-von-neumann-tho... ). Unlike most people who worked with computers for numerical abilities and business accounting, he was interested in information search and management. He coined the terms "information retrieval" and "descriptor" and is one of the pioneers of IR. While his ideas were reasonably widely known at the time, he self-published nearly all his papers as company white-papers. This makes it very hard to track down the original sources. I have a copy somewhere in my personal archives. This one was reprinted in the Bulletin of the American Society for Information Science and Technology, and is available from https://asistdl.onlinelibrary.wiley.com/doi/full/10.1002/bult.37 https://asistdl.onlinelibrary.wiley.com/doi/full/10.1002/bul... .
