They're the ones who did the actual testing/measurements. I had a box fan attached to a single filter (for wildfire smoke) but was unaware of how inefficient it was.
just to follow your logic. lets say I invent car. Corsi and Rosenthal measure it to discover how more efficient it is compared to horse, and from that point it's known as their invention
It's known as their technique (not invention) because it got popularized via of word of mouth. Same as the Fosbury flop or Larsen truss.
If you create some novel car design that gets discussed enough, maybe it will get popularized and get named after you. ie Bangle butt, for the E65 BMW 7 series.
