Georg Humann (8 December 1847, in Rellinghausen (now a suburb of Essen) – 18 January 1932, in Aachen) was a German art historian.
Humann represented an alternative perspective to that of the architect in charge, Peter Zindel, whose plans foresaw the gothicization of the westwerk.
After his house in Essen had to be sold in 1897 because of an inheritance dispute, Humann settled in Aachen, where he lived in the Vinzenzstift from 1900 and died in 1932.
His private library, with around 300 individual volumes on art history as well as his own work was donated by Humann to the Stadtbibliothek Aachen after his death.
Furthermore, during the preparation of his book about the Cathedral Treasury, he discovered that the wooden interior of the Golden Madonna was full of woodworm, prompting restoration work without which the figure would probably not have survived.
