first personality Dhirubhai Ambani

So, I decided to start with dhirubhai ambani when my wife suggested this (though she works in a Tata's company). She said u allready know few things about Ambani as u have seen Guru movie. I read wiki page of the prince of polyester. Now I know many things about this great man.
At the end I came to know about one more thing. there is allready a list of biographis of Indian enterprenuers which I wanted to make. But they have only 37 personalities, so I can start on others. But I am planning to first read few of them. I'll read Dhirubhai's biography first.

• Do you know about struggle of Dhirubhai Ambani ?
• Do you know that Vijjay Mallaya failed in approx 10 business? Do you know about Anu Aga ? Do you know about Gulu Mirchandani ?

This gave me more curiosity to know the life of these guys. So I have decided, I'll read about these guys, collect information about them and will share the information in a blog. I'll take one personality at a time. will do full case study about him.
So, with whoome I should start with?
