Legacy
In his laudatio for Müller in 2009, awarding the Great Cross of the Order of Merit of the Federal Republic of Germany, President Horst Köhler focused on Müller's ability to speak the language of both politics and economy, and enable dialogue between them. In the matter of nuclear power phase-out, he managed to represent the voters' wishes even though they were not his own view, and he always held constructive discussions with people representing different positions and interests. Köhler mentioned Müller's competence, calm manner, equanimity and dependability. In turning away from coal mining, he created a model of a socially responsible structural transition, with patience and tenacity. After his death, Schröder acknowledged Müller as a great economic leader who knew the rules of the game of both business and politics, which enabled him to turn opponents to partners. Jean-Claude Juncker, President of the European Commission, noted Müller's enormous expertise, dry humour and calm manner, achieving invaluable benefits for the German miners. Armin Laschet.
