Carl Icahn, the famed hard-nosed billionaire and corporate raider who attempted to seize control of Yahoo after the company rejected Microsoft's $50+ billion acquisition offer, has resigned his position as a member of the Yahoo Board of Directors, according to several reports.
In May 2008, he shook the company started by Jerry Yang (who was CEO at the time) by nominating a "dissident slate" of directors, which would have essentially given him control of the company. In the end, he received control of three seats on Yahoo's board and eventually helped force Jerry Yang out as Yahoo's CEO.
