Theodor Hörmann von Hörbach was an Austrian landscape painter.
He began his career in the Austrian Army and served during the Second Italian War of Independence (known as the Sardinian War in Austria), followed by service in the Austro-Prussian War. He reached the rank of Oberleutnant.
From 1873 to 1875, he studied at the Academy of Fine Arts, Vienna, with Eduard Peithner von Lichtenfels and Anselm Feuerbach. After that, he taught drawing and fencing at the Military Realschule in Sankt Pölten.
In 1884, he got married and retired from military service. He undertook several study trips and lived in Paris from 1886 to 1890, where he came under the influence of Impressionism. From 1890 to 1893, he lived in Znaim, then settled in Vienna, becoming a member of the Künstlerhaus.
