During the 1980s, activist investors such as Carl Icahn and T. Boone Pickens gained international notoriety and were often perceived as "corporate raiders" for acquiring an equity stake in publicly owned companies, like Icahn's investment in B.F. Goodrich, and then forcing companies to take action to improve value or rid themselves of rebel intruders like Icahn by buying back the raider's investment at a fat premium, often at the expense of the other shareholders.
