Former Chancellor Helmut Kohl, the architect of Germany's 1990 reunification and mentor to Angela Merkel, has died at age 87, his Christian Democratic Union party (CDU) said on Friday.

The mass-selling newspaper Bild reported that Kohl died at 9.15 a.m. Friday morning in bed at his home in Ludwigshafen, in western Germany, with his second wife, Maike Kohl-Richter, at his side.

Merkel, Germany's incumbent chancellor who grew up in communist East Germany before being appointed by Kohl to her first ministerial post, said he "changed my own life path decisively" by reuniting Germany.
