Where does the term "Hyzer" come from?

We all know the words hyzer and anhyzer, but did you ever stop and wonder where they came from?
I thought it might be German for "Turn." Dacsh Unt Hyzer!!!
The only bit of info I got after some online searching was this:
http://www.doubletongued.org/index.php/dictionary/hyzer/
According to the book “Frisbee” (ISBN#0-911104-53-4) by Dr. Stancil E.D. Johnson the term Hyzer is the discs angle of roll (Sideways tilt at “whelm"(the disc’s first period of flight)). The Hyzer Angle is named for H.R. “Fling” Hyzer, father of the “Flying Flutterball”.

I tried to verify that, but couldn't find another source to back up the claim that it was named after this H.R. Hyzer person.

Anyone?

Gee whiz. I always thought hyzer was the left-over name since the "turnover" shot was what happened after you drank too many Anheuser-Busch beers...but then, I don't really remember that much of the 70s...guess I had too good of a time
