After the death of her husband, Dorotka decided to pursue arts. She briefly studied painting and sculpture in
Basel before moving to
Paris in 1907. She had an
atelier at 21 Avenue du Maine,
Montparnasse, not far from her Paris home. She was friends with Russian-born painter
Marie Vassilieff, founder of the famous Paris Académie Russe (later Académie Vassilieff). She met many leading figures in the world of painting (Matisse, Chagall, Picasso, Van Dongen, Laurencin, and others), and also worked for a time in the Matisse Painting School. She also met the famous Croatian sculptor
Ivan Meštrović, with whom she remained in contact, as evidenced by her letters preserved in Meštrović's estate. In 1914, upon the outbreak of World War I, Dorotka was, as a citizen of Austria-Hungary, forced to leave France, and her assets in the country were frozen. ==Exile in Spain==
