Zygmunt Ajdukiewicz was a Polish realist painter of the late 19th century specializing in portraits, genre and historical painting. Ajdukiewicz, was born and raised in the Austrian sector of Partitioned Poland, settled in the imperial capital upon the completion of his studies, but maintained a close connection with his homeland. While in Vienna, he illustrated the epic novel The Deluge (Potop) by Polish Nobel Prize-winning novelist Henryk Sienkiewicz.
Zygmunt Ajdukiewicz was born in Witkowice near Tarnobrzeg in south-eastern Poland. He studied painting at the Kraków Academy of Fine Arts originally. From 1880 to 1882, he studied at the Academy of Vienna and, from 1883 at the Munich Academy under Johann Herterich, associated with the Munich School of naturalism. He settled permanently in Vienna in 1885 as popular painter of the Austrian court where he was also referred to as Zygismund or Sigismund von Ajdukiewicz. In 1893 he went to Paris. Back in Vienna, he worked on a long series of original artwork for the 24-volume encyclopedia initiated and sponsored by Prince Rudolf as evidence of his imperial achievements (Kronprinzenwerk). It was a major publishing project printed in German and Hungarian between 1886–1902 under the title Austro-Hungarian Monarchy in Word and Picture. Subsequent volumes were published long after Rudolf's death which took place in January 1889. Ajdukiewicz painted panels for the encyclopedia depicting various nationalities, ethnic groups and minorities represented in Austria-Hungary. He also produced a series of 12 paintings about the life of Tadeusz Kościuszko published in 1892 as an art-album by F. Bondy. He made a life-size standing portrait of Archduke Franz Ferdinand as a hunter (1913).
