[Ralph Hinkley]

Many years back, when The Greatest American Hero show was new, I was told that I looked like the star; William Katt.  He is the son of actors Bill Williams (birth name Herman August Wilhelm Katt) and Barbara Hale.  His parents worked as tv actors, also.  His father had a number of different character roles in the same show where his mother had a major part as the legal secretary (Della Street) for Raymond Burr in the classic tv program "Perry Mason".   Father and son also were together in one episode of a later Raymond Burr show titled "Ironsides".
I'm old enough to remember all of those shows, and still have my curly hair....  just gray instead of blonde.
