I'm wondering about important characters who demonstrate a significant knowledge of opera, ballet, symphonic music, literature, dining. So far I have:

Felix Unger
Charles Emerson Winchester
Diane Chambers
Frasier Crane
Niles Crane
Wilson Wilson
Giles French

Any others?

How about the Howells from Gilligan’s Island?

Margaret Drysdale (Beverly Hillbillies)
Millicent Schuyler Potts (Beverly Hillbillies)
Miss Jane Hathaway (Beverly Hillbillies)
Mother Douglas (Green Acres)
The Howells (Gilligan's Island)
Aunt Harriet Cooper (Batman)
Theodore Mooney (The Lucy Show)
Endora (Bewitched)
Maurice (Bewitched)
Amanda Bellows (I Dream of Jeannie)
Cathy Lane (Patty Duke Show)
Uncle Martin (My Favorite Martian)
Mr. French x 2 (Family Affair)
Miss Faversham (Family Affair)

We're led to believe Marie Barone (Everybody Loves Raymond) was quite accomplished on the piano, and was an avid opera fan.

Thanks for suggestions. Cathy Lane is a certain, I think along with Miss Jane. I had also thought about Maurice and maybe Marie.

Some of the others - like Mrs. Drysrale and the Howells - are certainly high society, but I don't know how knowledgeable they are supposed to be.

There's always Sonny Drysdale!

He certainly has the training. There's also the matched set of The Ptofessor and Arthur Dietrich. Dietrich seems to have more interest in the artistic side - Goethe festivals ans Swan Lake - but The Professor may just lack opportunity on the island.

Edit: I guess Ted Mosby, as well.

Yes on the castaway Professor.

Also Gidget's dad, Professor Lawrence, is constantly quoting highbrow literary sources.

Yes. Martin Lane is similar.

Wilson W. Wilson (Home Improvement)?

Groucho Marx in "A Night At The Opera"

“Now on with the opera. Let joy be unconfined. Let there be dancing in the streets, drinking in the saloons and necking in the parlor.”

The Pat Woodell version of Bobbie Jo Bradley was certainly well-read, if not "cultured."
