Fanny Maria Churberg was a Finnish landscape painter active in the latter half of the 19th century. In addition to her initial training in her home country, she studied in Germany and France, and her style primarily reflected the influence of her German instructors.
Churberg’s handling of landscape subjects, particularly those with rocky elements, are crisply defined, with visceral texture and strong compositions.
Unfortunately, I can’t find many online sources for her work, but some of those that are available feature a few high resolution images.
