In the 1980s, Roland Berger and Alfred Herrhausen, Chairman of the Management Board of Deutsche Bank, developed the concept of a European-style investment bank. Against this background, Deutsche Bank gradually acquired a qualified majority stake in Roland Berger from 1987 onwards. Deutsche Bank wanted to expand its advisory business to become the third pillar of its business alongside commercial banking and investment banking. After the assassination of Herrhausen by the Red Army Faction in 1989, however, cooperation came to a standstill. With the acquisition of Morgan Grenfell, the consulting business was less in focus at Deutsche Bank.
