I saw Hidden Figures this weekend, which brought back some early days for me when I worked in Langley’s Structures Directorate as a systems analyst. After scouring the web for documents, and reading Grier’s book, I still wonder whether the computation steps were organized in some sort of diagram that would be used by a planner (?) to guide the human computers. I’ve also reviewed Pickering’s legacy, the Handbook of Human Computation, and Human Computation by Law and von Ahn. If you review Willey (1969) “Manual for Reduction of Data” by Helen H. Willey (Supervisory Mathematician), there are many equations but no visual guides as to who does wha,t and the structured flow of computed variables by computers. Here is a nice NASA site with citations: https://crgis.ndc.nasa.gov/historic/Human_Computers But I do not see anything resembling a time-ordered process. Today, we might expect data flow diagrams, business process notations, or something of the sort. What did they use back then, or perhaps they created computational and data flow order without explicating documenting it? -paul Paul Fishwick, PhD Distinguished University Chair of Arts, Technology, and Emerging Communication Professor of Computer Science Director, Creative Automata Laboratory The University of Texas at Dallas Arts & Technology 800 West Campbell Road, AT10 Richardson, TX 75080-3021 Home: utdallas.edu/atec/fishwick Blog 1: medium.com/@metaphorz
