Siemens chairman says to stay on until 2018
Cromme, 71, has been on SIEMENS (SIE.XE) supervisory board since 2003, during which time he has seen off three chief executives ? two of them since he became chairman.
Cromme, a former CEO of German steelmaker Krupp, was also the driving force behind the 1999 mega-merger of Thyssen and Krupp.
