In the movie "Dead Poets Society", who was the picture of the sweaty tooth madman of?

Wasn’t it the poet, Walt Whitman?

He had sweaty teeth?
Can you post a link?

@filmfann No sorry. I don’t have a computer, and I am using my cell phone.

The one above the blackboard above Robin Williams’ desk is Walt Whitman, who wrote “O Captain, My Captain”, the poem that is a central part of a lesson by WIlliams’ charachter.

A A sweaty-toothed madman with a stare that pounds my brain – O Captain, My Captain

Not entirely sure but I think it was Walt Whitman. Although I must say the movie was amazing and I loved Niels’s character. I think it’s a great movie for the youth today and they can reflect on the importance of pursuing what they truly love.

Spoiler: I don’t agree with suicide (just so people don’t bash me on that)
