Another fun example is Deutsche Bank. Their first non-German leader (Anshu Jain, who didn't speak German) was made Co-CEO with an older German hand Jürgen Fitschen from the board. They pushed out Jain after 3 years, brought in a Brit John Cryan (who spoke German!) to co-CEO with Fitschen. Fitschen stayed on another year after which they finally let the non-German, Cryan run the place as sole CEO for 2 years before replacing him with another German as sole CEO. So in total there were 4 years of non-German co-CEOing with a German, 2 years of a non-German actually being sole CEO, and then back to a German again like the rest of their 153 year history.
