Franz Kafka was born in Prague in 1883. He spent most of his life in the city, grew up in a German-Jewish environment, and wrote in German. Among his most famous works (novels, short stories, etc.) are Das Urteil (The Judgment), Das Schloss (The Castle) and Der Prozess (The Trial). In 1923 Kafka moved to Berlin, but his tuberculosis soon got worse, and a year later he died at a hospital near Vienna. Quite a few of his works were not completed and edited/published after his death.

Design Competition - Overview

Keep in mind that the "eagle side" of every collector coin has to have the country name (Bundesrepublik Deutschland), the federal eagle, the twelve stars of Europe, the face value, and the year and mint mark. That limits a designer's artistic freedom of course ...
Winning Design: Frantisek Chochola
The winning design, depicted above, shows Kafka's face "embedded" in quotes from his works. On the left, St. Vitus Cathedral in Prague. This combination of author/portrait, "his" city and his works is what the jury liked most about this design.

Second Prize: Erich Ott
This design shows a portrait of Franz Kafka. The jury emphasized the good "balance" of this one; both sides have the core design in the middle third.

Third Prize: Heinz Hoyer
Hoyer's theme was not so much the author but what he conveys in many of his works. He shows a tiny Kafka at a desk in the middle of a maze. In this case the jury argued that the design, although formally interesting, cannot be recognized as honoring Kafka.

Fourth Prize: Werner Mebert
Mebert combined a portrait of the young man (modeled after a photo taken in 1906 when Kafka became a Doctor of Law) and his signature. According to the jury, that side is well done but does not correspond well with the eagle side.
