Called by Time magazine the "Warren Buffett of Saudi Arabia," Prince Al-Waleed bin Talal is a member of the Saudi royal family, as well as a Lebanese citizen through his mother. Though he is the nephew of Saudi King Abdullah, he is not in line to rule Saudi Arabia and has largely stayed out of politics. He is an entrepreneur and international investor with a net worth estimated in 2006 at $20 billion, and he is ranked as the eighth richest person in the world by Forbes.

He has made large investments, through his Kingdom Holding Company, in Citicorp (NYSE:C), AOL (NYSE:TWX), Apple (NASDAQ: AAPL), Motorola (NYSE:MOT), Rupert Murdoch's Fox News Corp. (NYSE: NWS), and other technology and media companies. His real estate holdings have included stakes in the Four Seasons hotel chain, the Plaza Hotel in New York, the Monte Carlo Grand Hotel in Monaco, and Euro Disney. In 2005 he purchased the Savoy Hotel in London for £250 million.

In 2001 Prince Al-Waleed's donation of $10 million dollars to New York City in the wake of the September 11 World Trade Center attack was rebuffed by Mayor Giuliani. In 2005 he donated $20 million to the Louvre for the construction of a wing to house the museum's vast collection of Islamic art, and another $20 million to Harvard and Georgetown Universities for Islamic studies programs. He has also donated to centers for American studies at universities in the Middle East, such as the American University in Cairo. He is believed to donate more than $100 million annually to charities throughout Asia, Africa, and the Middle East.
