It didn't do Dan Tayloe much good did it?? No one who uses the Tayloe mixer in a commercial radio has paid Dan a dime.
The Tayloe detector patent (expired) was filed by Motorola, and any license fees would presumably go to Motorola. As a Motorola employee Dan would have been paid a salary and other benefits by Motorola. So arguably, he got paid...
It's an interesting history too, the quadrature sampling detector was published by a Dutch author in ARRL's QEX at least 10 years prior to Dan's invention, and a Japanese radio amateur even pre-dates that by a couple of years. Like many inventions they seem to pop up in multiple places and it gets sometimes contentions who was first.?
I myself certainly first became aware of the QSX through Dan Tayloe's work.?
