James Dimon is a real financial shark.

James "Jamie" Dimon was born on 13 March, 1956. He is chairman, president and chief executive officer of JPMorgan Chase.

According to the Bloomberg Billionaires index, Dimon, the CEO of JPMorgan Chase, joins his mentor Sandy Weill as one of the few banking executives to become a billionaire.

He received a $23 million pay package for fiscal year 2011, more than any other bank CEO in the United States.[9] Dimon received $20 million in compensation for his work in fiscal year 2013.

He majored in psychology and economics at Tufts University. During one summer's break from Tufts, he worked at Shearson. After graduating, he worked in management consulting for two years before enrolling at Harvard Business School, along with classmates Jeffrey Immelt, Steve Burke, Stephen Mandel and Seth Klarman. During the summer at Harvard, he worked at Goldman Sachs. He graduated in 1982, earning a Master of Business Administration degree as a Baker Scholar.

After graduation, Sandy Weill convinced him to turn down offers from Goldman Sachs, Morgan Stanley, and Lehman Brothers to join him as an assistant at American Express. Although Weill could not offer the same amount of money as the investment banks, Weill promised Dimon that he would have "fun".

In a power struggle, Weill left American Express in 1985 and Dimon followed him. The two then took over Commercial Credit, a consumer finance company, from Control Data. Dimon served as the chief financial officer, helping to turn the company around. Through a series of unprecedented mergers and acquisitions, in 1998 Dimon and Weill were able to form the largest financial services conglomerate the world had ever seen, Citigroup. Dimon left Citigroup in November 1998, after being asked to resign by Weill during a weekend executive retreat.

In March 2000, Dimon became CEO of Bank One, the nation's fifth largest bank. When JPMorgan Chase purchased Bank One in July 2004, Dimon became president and chief operating officer of the combined company.

On December 31, 2005, he was named chief executive officer of JPMorgan Chase and one year later, on December 31, 2006, he was named chairman of the board.

Dimon was named to Time magazine's 2006, 2008, 2009, and 2011 lists of the world's 100 most influential people. He was also named to Institutional Investor‍ '​s Best CEOs list in the All-America Executive Team Survey from 2008 through 2011.
