Dresdner Bank
Perella left the firm for Morgan Stanley in 1993. Wasserstein stayed through the takeover by Dresdner Bank, but left the firm in 2002 to head investment bank Lazard, until his unexpected death in 2009. The investment banking business of Dresdner Bank changed its name to Dresdner Kleinwort Wasserstein as a result of the deal. In 2006, four years after Wasserstein's departure, it dropped Wasserstein's name.
