Have there ever been celebrities like Jim Cramer before in history? Are there in other countries?

I'm wondering if there have ever been wall street celebrities like Cramer before or at the same time as him.

To me he is a unique character in the stock market world and obviously things wouldn't be the same without him, especially for cnbc.

Before Cramer were there other wall street celebrity types comparable to him?

Are there any “Jim Cramer” or mad money shows in other countries?

Thanks.
