I didn’t know Mark Pittman, a reporter at Bloomberg News. We emailed a few times about the landmark lawsuit he instigated challenging Federal Reserve secrecy. I do know that Pittman is a genuine hero in a story which has very few.

He died too young last year, at 52. From what I gather, Pittman combined rumpled style, intellectual firepower and fierce persistence. The fight he waged to get the Fed to open its books serves as a lasting legacy and a strong reminder that one savvy, dogged person can make a real difference.

Earlier this month, Pittman’s employer, Bloomberg News Service, won yet another round in its fight with the Fed.
