Maria Bartiromo's husband may have been a very unfamiliar face to many people out there, but he is actually just as successful as his better half, or even better.

You may have known Maria Bartimoro as the famous journalist, magazine columnist, author, and as a former CNBC anchor-reporter, but there are certainly a lot of things you don't know about her, even her husband's identity, career, and whatnot.

So who is Maria Bartiromo's husband? It's Jonathan Steinberg or Jonathan Laurence Steinberg to be exact.

He is the founder of WisdomTree Investments, Inc., which is otherwise known Individual Investor Group, Inc. He has been the Chief Executive Officer of the company since October 1988 and he is also the President of various funds of WisdomTree fund complex.

Johnathan Steinberg became Maria Bartiromo's husband when they married in 1999. The famous journalist was then building her name as a tv personality when she joined CNBC as an anchor.

Following their marriage, Jonathan has landed a number of gossip columns as "Maria's husband" and was always envied and denigrated for having a wealthy upbringing and being married to a famously beautiful woman.

Nevertheless, all these changed when his company flourished and became undeniably successful in reinventing index funds.

In 2007, Maria Bartiromo's husband was featured on Forbes for being one of the most successful men in the business industry.

At the start of this year, Business Week has also recognized Steinberg's accomplishments and has even highlighted his credentials when it comes to handling top positions in a number of companies and publications.

While The Richest has disclosed that Maria Bartiromo has a net worth of $22 million as of 2012, no one and nothing has been published as of late on how much money her husband makes. But given the fact that WisdomTree Investments Inc. is a multi-billion company, it's not that hard to do the math and say that it's not only Steinberg who got lucky in marrying the beautiful author.
