Dora Livia Felicia Maria Duncker (28 March 1855 – 9 October 1916) was a German writer of novels, short stories, essays, poems and stage works.
She also undertook significant "study trips" through Austria—notably in the Tirol, Northern Italy and Switzerland.
Both at her family home in Berlin, and at von Piloty's home in Munich, she became part of a wider network of the arts and literature establishment that included the artists Hans Makart and Franz von Lenbach along with the writer, Paul Heyse.
The marriage was quickly followed by separation and then ended in divorce, however it also resulted in the birth of a daughter.
Following the collapse of her marriage Dora Duncker supported herself as a prolific freelance author and contributing editor.
