The Leading Mid-European Astronomer Marian Wolfgang Koller

Marian Wolfgang Koller used to be considered the very best astronomer from Carniola next to Augustin Hallerstein. Today, his work connected with the Dalton Minimum is again in limelight as the alternative explanation of global warming phenomena. Koller wrote precise notes of six semestrial courses of Josef Stefan to promote Stefan’s talents. By using the international connection of his patron Koller, Stefan published at least twenty articles in the British Philosophical Magazine, some of them also in Paris and Geneva.
