Most successful real estate investors?

[Justin Foster]

What are some names of really successful real estate investors?

I understand this might be a difficult question as investors usually aren't celebrities and don't become widely known, but I'd like to know about any really successful RE investors, past or present.

I like to read the biographies of people that have what I want and see what they went through to get there.

I didn't care for the Rich Dad Poor Dad books. I kept reading the next one hoping there would be some details on exactly what he did, but it was all general info. I think they are good for inspiration and the general idea of investing, but lack any real substance when it comes to RE investing.
