Who were the economists who made lots of money in the financial markets? I prefer to learn economic theories from economists who made lots of money from the financial markets and were aided by their economic ideas. Who were they? What are the notable economic theories did they formulate?
At university classes, I always learned that the only economist who ever became rich was Ricardo. However, Ricardo was already rich before becoming an economist. 

This article seems support this claim. It also gives an explanation for the lack of rich economist:


  If becoming wealthy is your goal in studying economics, you may be disappointed.  Although most economists make a good living, few have become rich from their knowledge of economics. In fact, if economists had some secret for making money in, for example, the stock market, they would likely be using those secrets to their own financial advantage [...] In short, economics won’t necessarily make you richer, but it may keep you from making some decisions that would make you poorer.
