Mike Evans and Eric Monte created Steptoe and Son?????

Cooley High - yes. Good Times - yes. What's Happening!? Yes (see Colley High.) Jeffersons? Disputed but got a settlement.

But not All In The Family, One Day at a Time, Mary Hartman, Maude, A.k.a Pablo and CERTAINLY NOT Sanford and Son, or Sanford Arms, Grady or Sanford!

And Lear developed and/or produced the shows - he doesn't have "created by" on the vast majority.

You're right though - Norma Lear is a Jew.
