CNBC's Mark Haines called 'nicest gruff guy you will ever meet'

Wall Street is taking the anchor's unexpected death really hard. He had been a fixture on the financial network for many years, but more than that, he was a calming voice for investors, especially during 9/11 and the Wall Street meltdown. His look was definitely a draw - unlike much of the network's eye candy, Haines was described by Fast Company as "a butcher forced to wear a business suit." The gruff guy quote is from Jonathan Wald, formerly CNBC's senior vice president of business news. No word yet on cause of death. From DealBook:

Mr. Haines became known as a wry, if sometimes curmudgeonly, emcee. But with his glasses perched on the end of his nose, he also became known as a sharp-tongued interviewer, often bluntly battling with guest chief executives over their companies.
