Paul Daniel “Ace” Frehley. Lots of history here:
https://en.wikipedia.org/wiki/Ace_Frehley
The part about his nickname is funny.
Dude grew up as a Lutheran!
Frehley and Kiss were not exactly my cup of tea, but, he had a unique style of playing, and played well. He was completely self-taught on guitar, evidently.
The big decline in my own Dad, at a slightly older age, also started with a fall and head injury... Dad lived a pretty healthy lifestyle, which may be part of how he partially recovered B4 an eventual slow slide down...
RIP to Ace and prayers for his family and friends. That had to be a tough decision. :-(
For those who only know of his work with KISS please listen to this outstanding instrumental, "Fractured Mirror", from his solo album from 1978.
I'd been using a tagline that applies to Ace without ever associating it. Good voyage and thanks for the good works, sir.
