Nikolaus Dumba (Greek: Νικόλαος Δούμπας; 24 July 1830, Vienna – 23 March 1900, Budapest) was an Austrian industrialist and liberal politician.
[1] In 1817, Nikolaus' father Stergios, an immigrant to Vienna from a family of Aromanian[2][3] or Greek[4][5] descent from Vlasti, a village then part of the Ottoman Empire and today in Greece, became a merchant.
Nikolaus attended the Akademisches Gymnasium and spent the revolutionary years of 1847-48 with his brother Michael at the residence of the Austrian Ambassador Anton von Prokesch-Osten in Athens.
He was a close friend of Hans Makart, Gustav Klimt and Carl Kundmann and was a strong promoter of contemporary art.
In the city of Serres, near his father's hometown, he founded an orphanage and contributed to the construction of a vocational school, under the aegis of his friend and fellow Greek politician, Georgios Averoff.
