Robert Kasimir began drawing at age 4, taught by his grandfather Alois. He made his first etching at age 5. He graduated from Vienna schools and attended the Technological College before switching to the Academy for Graphic Art, where he studied under Professor Hans Frank, a painter and graphic artist.

Robert inherited the talent of his famous parents, Luigi Kasimir and Tanna Kasimir-Hoernes. Early in his career Robert also worked in oil, signing his paintings, “R.K.”. His idols were two well-known 19th Century Viennese artists, Rudolf von Alt and Ferdinand Waldmueller. In 1936 Robert Kasimir came to the United States for a year of study at the Academy of Fine Arts, Philadelphia. In 1938 he was drafted into the army. He was sent to several fronts (Belgium, Holland, France, Russia) as a war reporter. He did many drawings during the war but only photos of them remain, for the originals were burned during the bombing of Berlin. In 1961 Robert opened his own printing shop in Vienna, where he printed his own etchings and those of Luigi and Tanna. Following his father’s death in 1962 he began signing Luigi’s etchings “n.1. Luigi Kasimir” (“n.1” is the abbreviation for Nachlass, meaning “from the estate of” in German). Since his mother’s death in 1972 he has signed her etchings, “n.1. T.K. Hoernes”.

Kasimir was a consultant to the Austrian Government as a graphic arts expert. Today, his etchings are housed in many great print collections, including the New York Public Library, and many European Museums.
