In the American TV show "Happy Days" what was 'Potsies' full name?

I know this is about Potsie, but I loved The Fonz so much that I had socks with his picture on them! Haha! Fond memories of Tuesday nights at 8:00!

"Love, American Style" was the name of one show, not two.

Great show. ..everyone on the show was great…. Sad about Erin Moran ..
