I imagine that the market for organs wasn’t exactly robust in 1937, but they had to do what they could – so they pitched this one at the Scientific American audience with the assurance that actual empirical principles undergirded this organ. Let us show you some graphs to prove the point.

Side note, and hardly an irrelevant one: in the olden days, testimonials often had the exact address of the person who sent in a glowing econium; in this case we have Mr. E. L. Davis, a young man who was obviously doing okay. He could afford a $1200 organ, and he lived on a nice street.

Really: He lived here.
