Please. As is true of most financial services institutions, Citi has shuffled the deck so often since the distant days when Wriston ran the place that I'm sure there's no trace of him left in the organizational DNA. The last link with the Wriston era was broken when Wriston successor John S. Reed left after losing a power struggle with Sandy Weill, who'd merged with Citi as CEO of Travelers Group. The lasting (so far) monument to Weill's victory is the red arc that now sits triumphantly atop the "citi" in the Citibank logo -- the arc represents the umbrella that was the symbol of Travelers in its days as a humble insurer, before getting turbocharged by Weill.
